How this table was made

Both charts are the manufacturers' published colour lists as RGB approximations, the same data Ink/Stitch ships. Each Sulky Rayon colour is converted to CIELAB and compared with every Isacord Polyester colour using CIEDE2000, which weights lightness, chroma and hue the way people see them; the closest wins and its distance is shown. ΔE under 1 is indistinguishable, under 2.3 very close, under 5 close, under 10 noticeable side by side, over 10 a different colour.

Where the charts disagree most

The Sulky Rayon colours with the weakest Isacord Polyester match are Black Cherry 1183 (ΔE 12.6), Cloister Brown 1131 (ΔE 12.1), Dk. Tawny Brown 1059 (ΔE 12.1), Sable Brown 1186 (ΔE 11.7), Smokey Gray 1240 (ΔE 11.3), Hedge Green 1272 (ΔE 10.9). For those, pull the two nearest cones and hold them against the artwork in daylight rather than trusting the number.

Converting a whole design

Drop the stitch file on the thread colour converter to match every block at once and print the result as a colour sheet. Chart values are approximations, not spectrophotometer readings; confirm a customer's brand colour against a physical thread card.
