About ThreadMatch
ThreadMatch is a free tool for embroiderers who need to swap one brand's thread number for the closest color in another brand — when a design calls for Isacord but you stock Marathon or Gunold, or when a customer specifies a Pantone color.
Data sources and accuracy
- Thread colors come from the brand palettes distributed with the open-source embroidery software Ink/Stitch (GPL-3.0). Each palette holds the manufacturer's screen RGB values.
- Pantone values are from the MIT-licensed pantone-colors table of approximate sRGB values. PANTONE® is a trademark of Pantone LLC; these are not official color definitions.
- Matches are computed in CIELAB with the CIEDE2000 color-difference formula and may differ from the manufacturers' official conversion charts.
- Monitors, thread sheen, weight and dye lots all change how a color looks. Always confirm with a physical thread color card.
