What Is DMC?
DMC stands for Dollfus-Mieg et Compagnie, a French textile company founded in 1746. For most of its history, DMC was known primarily for manufacturing embroidery threads — the six-stranded cotton floss used in cross-stitch, needlepoint, and hand embroidery. The company developed a comprehensive color numbering system to standardize its thread range, and that system has since become the de facto global standard for color coding in the needlework industry.
Diamond painting arrived as a craft relatively recently (around 2015) and borrowed the DMC numbering system for its drill colors. Because the system was already widely understood by crafters and because many early diamond painting enthusiasts came from cross-stitch backgrounds, adopting DMC codes was a natural choice. Today, virtually every diamond painting supplier worldwide sells drills labeled with DMC codes, making the system the universal language of the craft.
How the DMC Numbering System Works
DMC codes are not organized in a simple sequential gradient from light to dark or from one hue to another. The numbering appears arbitrary at first glance — and historically, it was largely that, growing organically as new colors were added to the line over decades. However, some useful patterns exist within the system that make navigation easier.
Special Codes
Several codes fall outside the standard numerical range and describe special colors or finishes:
- blanc — Pure white (the most commonly used white in diamond painting)
- ecru — A warm off-white or cream color, slightly yellower than blanc
- B5200 — A bright white, slightly cooler and more intense than blanc
Ranges and Families
While the DMC range spans from single-digit codes to four-digit codes above 5000, most diamond painting drills use codes in the range of DMC 150 to DMC 3899. Codes in the 3700s and 3800s were added relatively recently to extend the range with additional shades. Numbers like DMC 3756 (ultra very light baby blue) and DMC 3865 (winter white) fill in gaps in the gradient that were not well-served by earlier codes.
What the Numbers Don't Tell You
Unlike some other systems (Pantone, for example), DMC numbers convey no information about hue, saturation, or value. DMC 321 is red. DMC 322 is a medium dusty blue. They are adjacent numerically but unrelated visually. This means there is no shortcut to understanding the color range — you need a visual reference chart or the physical color card. Diamond Painter's color palette viewer shows the actual colors alongside their codes, which is the most practical reference for digital work.

DMC Color Families Explained
While the numbering system is not organized by color family, the DMC range does cover a comprehensive set of hue families. Here is an overview of the major families and roughly which codes they include — this is a practical guide rather than an exact catalogue.
Reds and Pinks
Covers everything from intense crimson and fire-engine red through dusty rose, coral, salmon, and pale blush. Notable codes include DMC 321 (Christmas red), DMC 347 (very dark salmon), DMC 602 (medium cranberry), and the 3685–3689 range (mauve and antique mauve). Pinks extend into the 3706–3708 range (melon) and the 151–156 range (dusty rose gradients).
Oranges and Corals
A relatively small but useful family covering warm oranges, burnt orange, pumpkin, and terracotta shades. Key codes include DMC 740–742 (tangerine range), DMC 946 (medium burnt orange), DMC 900–919 (red orange through dark red orange). Terracotta shades appear around DMC 3830–3832.
Yellows and Golds
Ranges from lemon yellow through warm yellow, goldenrod, and deep antique gold. DMC 444, 445, 725–727 cover primary yellow tones. Golds and ochres appear in the 680–783 range. Pale topaz shades (DMC 725–3855) add warm peachy-gold options useful in skin tones and sunlit landscapes.
Greens
One of the largest families, covering yellow-greens, grass greens, forest greens, olive, sage, hunter, and dark emerald. The 163–166, 470–503, and 580–699 ranges are all greens of various values and warmth. Muted sage and khaki greens appear around DMC 523–524. For botanical subjects, the green family is especially important to understand well.
Blues
Covers sky blue, cerulean, cobalt, royal, navy, slate, and steel blue. The 312–336 range covers navy and very dark blue. The 517–519 range covers medium-dark wedgwood. Baby and powder blues appear in the 747–775 range. DMC 796 is a medium-dark royal blue particularly popular in diamond painting skies.
Purples and Violets
From pale lavender through medium violet, purple, and deep plum. Light lavenders appear in the 210–211 range. Medium violets are around 550–553. Plum and dark mauve run through 3041–3042 and 327. The 3836–3838 range adds additional light grape and lavender options that are useful in floral subjects.
Browns and Tans
A critical family for portraits, animals, and landscapes. Covers everything from pale sand through warm tan, medium brown, dark brown, and very dark coffee. The 420–434 range covers hazel to dark brown. DMC 437–841 provides tan to beige gradients. Skin tone browns appear in the 3770–3777 range. Chestnut and mahogany tones are around 300–302.
Greys, Black, and White
Essential for shadows, outlines, and neutral areas. The 317–318, 414–415 range covers medium-dark to light steel grey. Blue-greys appear around 157–160. Warm greys are in the 640–642 range. DMC 310 is the standard black. For white, blanc is the most commonly used; B5200 is an ultra-bright alternative.
How DMC Codes Are Used in Diamond Painting
In diamond painting, DMC codes serve two purposes: they identify the specific color of each bag of drills, and they appear on the canvas legend to tell you which color goes in which symbol. Every symbol on your canvas has a corresponding DMC code in the legend, and every bag of drills in a kit is labeled with that same code.
Because the system is standardized, the same code means the same color across different kit manufacturers and drill suppliers. DMC 321 drills from a Chinese supplier and DMC 321 drills from a European one will be the same shade of red. This standardization is what makes it possible to reorder specific colors, substitute from other suppliers, or share pattern files globally without any confusion about what color is intended.
Substituting Unavailable Colors
Occasionally a specific DMC color is out of stock, discontinued in drill form, or unavailable from your preferred supplier. In these cases, finding a close substitute is straightforward if you approach it methodically.
Finding Adjacent Colors
Within each color family, most shades come in gradients of 5–6 values from light to dark, with each step being only marginally different from the next. If DMC 3750 (very dark antique blue) is unavailable, DMC 336 (navy blue) or DMC 823 (dark navy) are close enough that most viewers will not notice the difference. The key is to stay within the same hue family and match the approximate value (lightness or darkness) of the original.
Using the Pattern Generator to Merge Colors
If you are working from a custom pattern generated with Diamond Painter, you can use the color replacement tool to swap a hard-to-find color for one that is available, before finalizing your drill order. This is often better than substituting after printing — you get to see how the substitution affects the overall pattern before committing to it.
Most Popular DMC Colors in Diamond Painting
Certain DMC codes appear in diamond painting patterns far more frequently than others — either because they represent commonly needed shades (neutral greys, skin tones, sky blues) or because they are particularly beautiful as drills.
| Swatch | DMC Code | Name | Common Use |
|---|---|---|---|
| blanc | White | Highlights, backgrounds, fur, snow | |
| 310 | Black | Outlines, pupils, very dark shadows | |
| 434 | Light Brown | Animal fur, wood, warm skin tones | |
| 3325 | Light Baby Blue | Skies, water, light blue areas | |
| 321 | Red | Bold red elements, flowers, clothing | |
| 3347 | Medium Yellow Green | Foliage, natural greens | |
| 318 | Light Steel Grey | Mid-tone shadows, silver elements | |
| 738 | Very Light Tan | Light skin tones, sand, cream areas |
How Diamond Painter Assigns DMC Codes
When you upload a photo to Diamond Painter and generate a pattern, the tool needs to reduce potentially millions of colors in your image to a small palette of real DMC drill colors. This process — called color quantization — works in several steps.
First, the tool clusters the colors in your image into groups using a perceptual color distance algorithm. Perceptual distance accounts for the way human vision is more sensitive to some color differences than others — a slight difference in skin tone is more noticeable than the same numerical difference in a background color. This produces a set of representative colors that best characterize your image.
Second, each representative color is matched to the nearest actual DMC color in the tool's database of 457 authentic DMC codes. The matching uses the CIE76 or similar perceptual distance metric rather than simple RGB distance, which produces more visually accurate results. The tool then replaces every pixel in the image with its matched DMC color and generates the pattern grid.
The result is that every color in your Diamond Painter pattern has a real, orderable DMC code attached to it — one you can search for on any drill supplier's website and be confident of receiving the right color.
Buying DMC-Coded Drills
With your DMC color list in hand (either from a kit's legend or from Diamond Painter's export), ordering the right drills is straightforward. Most major diamond painting suppliers sell individual color bags organized by DMC code, and you can use the code to search directly.
When buying by the bag for a custom project, estimate your drill counts from the pattern and add 10–15% extra as a buffer. Running out of a specific color partway through a large section is frustrating; having a hundred extra drills left over at the end is not a problem — they go back in the storage container for future use.
