Pattern and color data methodology

01 · Data principles

Identifiers and screen colors are different data

A catalog identifier and name tell you which product entry a row refers to. A hexadecimal value is only a digital approximation used for previewing and computation. mybeadpattern does not treat an sRGB hex value as an official physical color measurement.

Practical rule: use codes to gather materials, but compare difficult shades with the physical bead or floss under the lighting where you will work.

02 · Pattern selection

What the Small Patterns labels mean

Current version: pattern-selection-2026.07.28

The 20 designs are curated from Pixymoji by SpicyGame, released under CC0 1.0 Universal. We adapted previews and colors for the editor and excluded recognizable brands, characters and flags.

No card publishes “community hits,” marketplace volume, autocomplete volume or a similar demand number. Keyword research can guide which collection page to build, but it does not rank the individual patterns shown on this page.

03 · Fuse-bead reference data

Bead palettes and source policy

Current version: bead-palettes-2026.07.28

The editor currently carries 648 rows across five product lines. Codes and names are catalog references. Browser colors are community-maintained approximations assembled from the public beadcolors dataset and public Bitbead color charts, then checked for valid unique codes inside each palette.

04 · Fuse-bead matching

How pixels become bead colors

Current version: color-match-1.0.0

1. Hexadecimal palette values are interpreted as sRGB and converted to CIE Lab using a D65 white point.
2. Photo mode reduces the image with a deterministic median-cut quantizer. Pixel-art mode preserves hard edges with nearest-neighbor resizing.
3. Each resulting pixel is assigned to the allowed product color with the smallest squared Euclidean distance in Lab space—equivalent to ranking by CIE76 distance.
4. “My bead box” filters the candidate list before matching, so unchecked colors cannot appear in the result.

This method is deterministic for the same image, settings and palette version. It is a practical screen-space match, not a spectrophotometer measurement.

05 · Bracelet floss references

DMC planning palette

Current version: dmc-reference-1.0.0 · matching method: dmc-match-1.0.0

The Alpha Pattern Generator uses a curated 26-color planning set selected to cover common light, dark and saturated bracelet colors. It is not the complete DMC catalog. Codes and common names are maintained as product references and checked against DMC’s public six-strand embroidery floss listing. The hex values are mybeadpattern screen approximations rather than DMC color calibration data.

Image-to-DMC method

1. Pixels with alpha below 48 are ignored while dominant colors are selected.
2. Every remaining sRGB pixel is compared with the 26 planning colors using a red-mean weighted RGB distance.
3. Matched occurrences are ranked and the requested two-to-eight most-used planning colors are retained.
4. The final knot grid is remapped to that retained palette; transparent cells use the selected background reference.

06 · Limits and verification

What can change the physical result

• Displays, color profiles and browser rendering can make the same hex value look different.
• Bead and floss dye lots, age, finish, translucency and production changes can alter physical appearance.
• Ambient light, neighboring colors, knot density and ironing change perceived color.
• Transparent, glow, metallic, pearl and fluorescent products cannot be represented faithfully by one opaque sRGB swatch.
• Brand availability and catalogs change. A listed identifier does not guarantee current stock in every region.

Before buying a large quantity or cutting all working threads, compare a small physical sample and print-scale test with the current pattern.

Versioning and change log

A source, code, name, hex value, matching equation or selection rule change receives a new version identifier here. A content-only clarification updates the page date without silently changing the checked-in palette.
