Convert thread numbers between brands. Enter a code (or colour name) from your source brand, pick the target brand, and we’ll find the closest visual matches.
How it works
We look up your source thread, convert its hex colour into Lab colour space, then rank threads in the target brand by perceptual distance (CIE ΔE). ΔE under ~3 is a very close match; 3–6 is close; higher means a noticeable difference. Always double-check against your fabric and lighting.
