Diamond Painting DMC Color Chart: The Complete Guide to Understanding, Using, and Organizing Your Colors
If you've ever opened a diamond painting kit and wondered what all those numbers on the drill bags mean — or felt confused by the symbol grid on your canvas — this guide is for you. The DMC color chart is the backbone of the entire diamond painting system, and once you understand how it works, everything from organizing your drills to replacing missing colors becomes dramatically easier.
Here's everything you need to know.
What Is the DMC Color Chart?
The DMC color chart is a standardized color reference system used across the diamond painting industry worldwide. Every color of drill in a kit is assigned a unique DMC code — a three or four-digit number — that corresponds to a specific, named shade. These codes tell you exactly which color belongs in which spot on your canvas, and they make it possible to source replacement drills, organize your stash, and even mix drills from different kits without worrying about color mismatches.
The system is the global standard for diamond painting. Whether you buy a kit from a supplier in the United States, Europe, or Asia, the same DMC number always refers to the same color. That universal consistency is what makes the system so valuable.
Where Does the DMC System Come From?
The DMC color chart did not originate in the diamond painting world. It comes from a French textile company called Dollfus-Mieg et Compagnie — DMC for short — which was founded in 1746 and has been producing high-quality embroidery thread for over 275 years. The color chart was originally developed to standardize the hundreds of thread shades the company produced, giving each one a unique code so that embroiderers could consistently match and reorder colors across different dye lots and production runs.
When diamond painting emerged as a craft in the early 2010s, manufacturers needed a color reference system that crafters would recognize and that could support a large, diverse palette. The DMC embroidery color chart was the obvious choice — it was already standardized, globally recognized, and covered hundreds of distinct shades. The system was adopted wholesale, and the same numbering codes used for embroidery floss are now printed on every diamond drill bag worldwide.
This heritage matters practically: it means you can cross-reference DMC diamond painting codes with DMC embroidery thread charts, find hex and RGB color equivalents online, and access a rich ecosystem of color management tools that the needlework community has developed over decades.
How Many DMC Colors Exist for Diamond Painting?
The core DMC palette contains 447 standardized colors. These span the full spectrum from bright primaries to subtle neutrals, and from deep jewel tones to soft pastels, providing enough variety to reproduce almost any photographic image or illustrated design in recognizable detail.
Beyond the core 447, the diamond painting palette has expanded in recent years. DMC introduced 35 new thread colors that have progressively been integrated into diamond painting drills, allowing for more nuanced color transitions and greater photorealistic depth in complex designs. Some retailers stock these expanded shades; others work only with the core 447. When ordering replacement drills or custom kits, it is worth checking which range your supplier carries.
In addition to standard colors, you will encounter several specialty drill categories:
AB Drills (Aurora Borealis) carry the standard DMC code but are coated with a special iridescent finish that produces a rainbow, color-shifting shimmer when light hits them from different angles. They are noted with "AB" alongside the DMC code — for example, DMC 310 AB for iridescent black. AB drills are typically used as accents in specific sections of a design rather than throughout.
Neon drills are produced in fluorescent shades that go beyond the standard DMC range and glow vividly under certain lighting conditions. They are common in pop art and abstract designs.
Glow-in-the-dark drills absorb light and emit it in low-light conditions. They fall outside the standard DMC chart and are typically labeled separately by individual kit manufacturers.
How the DMC Chart Works on Your Canvas
When you open a diamond painting kit, you will find a color legend printed on the canvas itself, usually along one edge, or included as a separate reference card. This legend lists every DMC code used in the design, paired with the unique symbol that represents it on the canvas grid.
The canvas grid is printed with tiny symbols inside each cell — a triangle, a circle, a cross, a dot, and so on. Each symbol corresponds to a specific DMC code in the legend. Your job is to match the symbol to the right bag of drills and place the correct color in the correct cell.
This is the complete chain: symbol on canvas → legend → DMC code → drill bag label. Once you understand that chain, reading any diamond painting canvas becomes intuitive, regardless of which brand or design you are working with.
Some canvases also print the DMC number directly in each cell rather than using abstract symbols. This format is easier to read at a glance and is increasingly common on higher-quality kits, though it requires slightly larger cells to accommodate the text.
Understanding DMC Color Numbers
DMC codes are not assigned in a logical color sequence — the numbers do not run from light to dark, or from warm to cool. They are a legacy numbering system developed over centuries of textile production, and the codes reflect historical additions to the DMC thread catalog rather than any color logic.
This means that DMC 310 (black) and DMC 311 (a medium navy blue) are neighboring numbers despite looking completely different. Meanwhile, highly similar shades may have codes hundreds of numbers apart.
A few well-known codes are useful to memorize:
DMC 310 is black — the most commonly used color in diamond painting, appearing in outlines, shadows, and dark backgrounds across countless designs.
DMC B5200 and DMC White are both whites, with subtle differences in warmth. B5200 is a bright, cool white often used for snow, clouds, and bright highlights. White (sometimes labeled DMC Blanc) is a warmer, slightly softer tone.
DMC 317 and 318 are a pair of medium and light grey that appear frequently in portraits and grayscale designs.
DMC 3371 is a near-black dark brown used heavily in hair, wood, and shadow areas.
For everyday use, you do not need to memorize any of these. Your kit's color legend tells you everything you need for each specific project. However, familiarity with common codes becomes helpful when sourcing replacement drills or identifying unlabeled drills from your stash.
Why DMC Codes Matter Beyond the Canvas
Understanding the DMC system goes beyond just completing your current project. Here is where it pays off in practical ways.
Replacing missing or depleted drills. Running out of a color mid-project is one of the most frustrating diamond painting experiences. If you know the DMC code, you can search any drill supplier for that specific number and order an exact replacement. Without the code, you are left trying to match colors visually, which is unreliable — particularly for subtle shades.
Mixing drills across kits. Because the DMC system is universal, drills with the same code from two different kits are the same color. This means you can top up depleted bags from your personal leftover stash, even if the drills came from a completely different project and supplier. One important caveat: drill finish can vary slightly between manufacturers. Two bags labeled DMC 321 may be fractionally different in surface sheen or size depending on their production source. For most paintings viewed at normal display distance this is imperceptible, but it is worth being aware of for high-detail sections viewed close up.
Building and using a personal stash. Experienced diamond painters accumulate leftover drills from every project. Stored and labeled by DMC code, this stash becomes an increasingly valuable resource — a way to fill gaps, supplement future kits, and even start small projects with colors you already own.
Sourcing individual colors for custom work. If you are designing your own diamond painting from scratch, or adapting a pattern from another medium, the DMC chart gives you a complete palette to work from. You can select colors intentionally, order individual bags, and build exactly the color range your design requires.
How to Read the Color Legend in Your Kit
Every diamond painting kit includes a color legend, and knowing how to read it well will save you significant time and frustration.
The legend is structured as a table. Each row contains the symbol used on the canvas, the corresponding DMC code, the color name, and sometimes a small color swatch. In some kits, a checkmark column is included so you can mark off colors as you place them.
Before starting a project, spend a few minutes cross-referencing the legend against your drill bags. Lay the bags out in the order they appear on the legend and confirm every code is accounted for. If any bags are missing, contact the seller before you begin work — stopping mid-project to wait for a replacement is avoidable if you check upfront.
Pay particular attention to colors that look similar on the legend. Shades like DMC 3799 (very dark pewter grey) and DMC 310 (black) can appear nearly identical on a printed legend but are distinct colors that each serve different roles in the design. If you are uncertain, hold the bags side by side in good natural light.
Dealing with Similar and Confusing Colors
One of the most common challenges in diamond painting is distinguishing between closely related shades. The DMC system covers 447+ colors, which means many neighboring codes look remarkably alike — particularly in the blue-grey range, the brown-tan range, and the pink-red range.
Several strategies help manage this.
Work with good lighting. Natural daylight renders color differences most accurately. Artificial light — especially warm yellow light — can make cool greys appear warmer and cause blues and purples to look more similar than they are.
Use a light pad. Beyond illuminating canvas symbols, a light pad changes the way color is perceived against the canvas surface, which can help distinguish similar shades more clearly.
Keep bags closed until needed. Leaving multiple similar-colored bags open simultaneously is a recipe for mixing. Open one bag at a time, complete that color in your working section, reseal the bag, and only then move to the next.
Never rely on color names alone. Names like "very light blue" and "light cornflower blue" give only a general sense of the color. Always match by DMC code, not by name.
If you suspect two bags have been mislabeled or mixed up, check the codes on the canvas legend, then compare the drills under bright daylight against any reference swatches you have. Physical DMC sample cards — available from embroidery suppliers — show actual drills or thread samples attached to a card and are the most reliable color reference available.
How to Organize Your Drills by DMC Code
Good organization built around the DMC system is one of the highest-leverage improvements you can make to your diamond painting experience. The time invested in setup pays back many times over during a project.
The simplest approach for an active project is to lay out each bag of drills in a row or grid in DMC code order, with the bag label visible. As you complete each color, reseal and set it aside. This keeps your working surface uncluttered and makes it easy to locate the color you need at any moment.
For long-term stash storage, small resealable bags, bead organizers, or multi-compartment storage boxes all work well. The key is consistent labeling. Write or print the DMC code on every container. Numerical order is the most practical sorting system for large stashes — it allows you to locate any specific code quickly by scanning through the range.
Some experienced painters create physical reference cards: a sheet or booklet where actual drills are glued or taped next to their DMC codes, creating a visual inventory of every color they own. This is especially useful for identifying "mystery drills" — unlabeled or separated diamonds whose bag has been lost.
Printable DMC color charts are widely available online as free PDF downloads. These show every standard DMC color with its code, name, and a printed color swatch, and can serve as a working reference document kept near your craft space. Bear in mind that printed swatches are only approximations — screen-to-print color rendering varies, and the actual drill color is always the definitive reference.
The Difference Between DMC Codes for Round and Square Drills
A common point of confusion: DMC codes are identical for round and square drills of the same color. DMC 321 in round drills is the same red as DMC 321 in square drills. The code describes the color only, not the shape.
This means you can use the same DMC chart for both drill types, and leftover round drills from one project cannot be used to fill gaps in a square drill project (the shapes won't fit together cleanly), but the colors will match correctly if needed in a compatible project.
AB drills also share their base DMC code with their standard counterparts. DMC 666 AB is the same red as DMC 666, simply with an iridescent coating applied. When ordering AB replacements, specify both the DMC code and the AB designation.
Making Your Own Physical DMC Color Sample Card
Among experienced diamond painters, one practice stands out as particularly useful: building your own physical DMC sample card using actual drills rather than printed swatches.
The concept is simple. Take a sheet of card stock or a small booklet and glue or tape a single drill from each bag alongside its DMC code. Work through your stash methodically, creating a visual inventory where the actual drill — not a printed approximation — represents each color.
The advantages are significant. First, you can distinguish similar shades by looking at actual drills rather than printed colors, which are subject to printing variation. Second, when you encounter an unlabeled drill (perhaps a bag whose label came off, or drills that mixed during a spill), you can hold the mystery drill against your sample card and find its match visually. Third, the card doubles as a stash inventory — you can see at a glance which colors you own and which you are missing.
This is a project best undertaken gradually rather than all at once. Add to your sample card whenever you start a new kit, using one drill from each new bag as you unbox it. Over time, the card becomes a comprehensive reference built from your actual collection.
DMC Codes and Custom Diamond Painting
If you are working with a custom diamond painting kit — where a personal photo has been converted into a canvas design — the DMC chart plays an additional role. The conversion software maps the colors in your photograph to the closest available DMC drill colors. The number of DMC colors used in the conversion directly determines the detail and realism of the finished painting.
Budget custom kits may convert your image using only 25–35 DMC colors, which produces a more posterized, graphic look with visible color banding. Higher-quality custom services use 50–80+ colors, allowing for smooth gradients, subtle skin tone transitions, and more faithful reproduction of complex photography.
When reviewing a preview of your custom canvas, pay attention to how many DMC codes appear in the legend. More codes generally means more nuance. For portrait subjects especially — where face and eye detail is critical — a higher color count is worth the additional cost.
Common Questions About the DMC Color Chart
Can I use DMC embroidery thread colors to identify my drills?
Yes, with limitations. The DMC codes are the same across embroidery and diamond painting, so a DMC thread color chart will give you the correct color name and approximate shade for any code. However, thread and resin drill colors are produced differently and may not match exactly. Use embroidery charts as a general reference, not a precise match.
Why do my drills look slightly different from the color chart online?
Online DMC color charts show digital color approximations, which vary depending on the monitor, color profile, and printing conditions. Actual drill colors are the definitive reference. Minor variation between the digital chart and your drills is normal and expected.
Can drills with the same DMC code from different manufacturers vary?
Yes. While the DMC code defines the color standard, individual manufacturers produce drills to varying degrees of accuracy. Slight differences in hue, saturation, or surface finish can occur between production runs and between suppliers. For most projects this is unnoticeable, but if you are mixing drills from different sources in the same section of a painting, compare them in natural light before placing.
What if my kit uses codes that don't match any DMC number?
Some manufacturers use proprietary color coding systems rather than DMC codes. In this case, the kit's color chart is self-contained and you will need to contact the seller directly to order replacement drills using their internal codes. This is one of the practical disadvantages of non-DMC systems, and one reason experienced painters prefer kits that use the standard DMC numbering.
Are the new DMC colors (the "New 35") widely available in drill form?
Availability varies by supplier. Major retailers are increasingly stocking drills in the expanded DMC palette, but not all suppliers carry every new code. If your kit includes codes above the classic 447 range and you need replacements, search specifically for suppliers who state they carry the expanded or updated DMC drill range.
Final Thoughts
The DMC color chart might seem like a technical detail at first — just numbers on bags — but it is genuinely one of the most useful systems in diamond painting. It turns a potentially chaotic process of matching hundreds of similar-looking gems into something organized, consistent, and replicable. It connects your current project to every project you will do in the future, building a stash that gets more valuable over time. And it gives you the language to source, replace, and discuss colors with precision.
Once you internalize the DMC system, it stops feeling like a chore to manage and starts feeling like a natural part of how you think about your craft. That shift — from puzzling over bags of colored gems to confidently navigating a standardized color palette — is one of the most satisfying steps in becoming a confident, capable diamond painter.
