DMC Thread Colors Explained: The Complete Guide

What is DMC?

DMC — short for Dollfus-Mieg & Compagnie — is a French textile company founded in 1746. Today they produce the world's most widely used embroidery floss: a 6-strand cotton thread sold in small skeins, colour-coded by number. If you've ever worked from a published cross-stitch pattern or bought a kit, the thread codes listed on it are almost certainly DMC numbers.

The current DMC range covers 452 colours of stranded cotton embroidery floss, plus specialty threads including metallic, light effects, tapestry wool, and pearl cotton. For cross stitch, the stranded cotton range (sometimes called DMC Mouline Speciale) is the standard. Each skein contains 8 metres of 6-strand floss — enough for a surprising amount of stitching when you use fewer strands.

The DMC Numbering System

The single most confusing thing about DMC thread for beginners is expecting the numbers to follow a logical order. They don't — at least not by color.

DMC numbers were assigned chronologically as colors were added to the range over 275+ years of production. When DMC introduced a new red in the 1900s, it got the next available number — whether that was in the 300s or the 800s. This is why DMC 321 is a bright red Christmas red, while DMC 3801 is a deep cranberry, and DMC 498 is a rich holiday red — the numbers don't cluster these related colors together.

Some general patterns exist (many blues are in the 700s and 3800s; many greens live in the 500s and 3300s), but these are rough tendencies from when batches were added, not a systematic coding scheme. The only reliable way to find a specific color is to look it up by number, name, or reference swatch.

The DMC numbering also includes some unusual sequences:

• Numbers in the 3000s and 4000s are mostly newer additions to the range, added in the late 20th and 21st centuries
• Blanc (white) and Ecru are named rather than numbered
• A handful of numbers have been retired over the years — if a pattern calls for a discontinued number, conversion charts exist to find the closest current equivalent

Color Families and Ranges

Despite the non-sequential numbering, experienced stitchers learn the rough neighborhoods of the DMC palette. Here are the approximate groupings worth knowing:

These groupings are approximate — many numbers straddle categories, and the best way to really learn the palette is to spend time with an actual color card or a searchable color tool. Use Brodette's DMC Color Finder to explore the full 452-color palette visually.

Choosing Colors for Your Project

If you're working from a published pattern, your color choices are already made — just follow the listed DMC numbers. But if you're designing your own pattern or converting a photo, choosing colors is where the real work begins.

Photo-to-pattern color matching

When converting a photo to a cross-stitch pattern, the key challenge is reducing thousands of pixel colors down to a workable palette — typically 10 to 30 DMC colors. The quality of this reduction determines whether the finished pattern looks recognizable or muddy.

Professional pattern software like Brodette uses perceptual color science (specifically the CIEDE2000 color difference algorithm in CIE LAB color space) to find the DMC colors that are closest to your photo's actual tones. This produces far better results than simple RGB matching, especially for skin tones, shadows, and desaturated colors where the human eye is most sensitive to differences.

Designing from scratch

For original designs, most stitchers start by selecting a limited palette and building the pattern within those constraints. Good practices:

• Work with the physical DMC color card if possible — screens show approximations, not true thread colors
• Choose colors under natural light, not artificial lighting, which shifts the perceived hue
• Consider contrast at pattern scale — colors that look distinct in the skein may blend together as 1mm stitches
• Leave room for highlights and shadows within each color family, even in a small palette

Understanding Dye Lots

A dye lot refers to the batch of dye used when a specific group of skeins was manufactured. Even when producing the same color, subtle variations in water chemistry, dye concentration, and processing time mean that skeins from different dye lots can have slight color differences — sometimes visible, sometimes not.

Modern DMC is very consistent and tightly controlled, making dye lot variation less of a concern than it was decades ago. However, for large projects — especially backgrounds covering many stitches — it's still good practice to buy all the skeins of a given color you'll need at the start, from the same batch if possible.

DMC skeins do not typically print dye lot information on the label the way yarn does, so buying from the same retailer in the same order is the practical approach for consistency. If you run short mid-project, finishing the background with a new lot may or may not be visible depending on the color — dark, saturated colors show lot variation more than light, unsaturated ones.

To estimate how many skeins you need before you start, use our skein calculation guide.

Alternatives: Anchor and Cosmo

DMC dominates the market in most English-speaking countries, but two other major brands are widely used and worth knowing about:

Anchor

Anchor (formerly J&P Coats) is DMC's main competitor in the UK and Europe. Anchor produces around 440 colors of stranded cotton, sold in similar skeins. The thread quality is comparable to DMC — the choice is largely regional availability and personal preference.

Anchor uses an entirely different numbering system. There is no simple formula to convert between Anchor and DMC numbers — you need a cross-reference chart. For example, DMC 321 (bright red) corresponds approximately to Anchor 9046. The colors are close but not identical; small differences in saturation and value are normal.

Cosmo

Cosmo (produced by Lecien Corporation in Japan) is a third major brand available in specialty needlework shops and online. Cosmo offers approximately 500 colors with a reputation for slightly richer, more saturated hues than DMC. Like Anchor, Cosmo uses its own numbering system — cross-reference charts are available but conversions are approximations.

Cosmo is harder to find outside Japan and Australia, and is less commonly specified in published patterns, but it's a good option if you want to expand your color range or find alternatives for discontinued DMC colors.

Cross-Referencing Between Brands

If you're working from a DMC-coded pattern but only have Anchor thread (or vice versa), you need a conversion chart. These charts pair each DMC number with the closest equivalent in the other brand's range.

Important caveats about thread conversions:

• Conversions are approximations, not exact matches. The DMC and Anchor palettes don't overlap perfectly — no brand has a perfect equivalent for every color in another range
• Color differences are more noticeable in large areas of the same color. For accent stitches or outlines, the approximation is usually fine.
• Multiple DMC colors sometimes map to the same Anchor equivalent — this is especially common at the ends of the spectrum (very light or very dark shades)

Storing and Organizing Your Threads

Thread organization is one of those things that seems trivial until you have 200 skeins and can't find DMC 3750. Most experienced stitchers converge on a few standard approaches:

Bobbins

The most common method: wind each skein onto a flat cardboard or plastic bobbin and write the DMC number on it. Bobbins can be sorted numerically in a box with numbered dividers, making it easy to find any color in seconds. This is the standard stitching shop recommendation for a reason.

Ring binders with card sleeves

Some stitchers wrap thread around cards and file them in a ring binder — similar to bobbins but more compact and visual. Thread cards with a sample taped to the card are especially useful for quick color comparison.

Digital stash tracking

For larger collections, a digital record of which DMC colors you own helps with project planning — especially for the frustrating problem of discovering mid-project that you're missing a color that was on your list. Brodette's thread stash tracker lets you build and maintain your DMC collection digitally, and shows you which colors from a given pattern you already own.
