How this table was made

Both charts are the manufacturers' published colour lists as RGB approximations, the same data Ink/Stitch ships. Each Robison-Anton Polyester colour is converted to CIELAB and compared with every Madeira Polyneon 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 Robison-Anton Polyester colours with the weakest Madeira Polyneon match are Cindy Purple 9088 (ΔE 16.5), Herbal Blue 9103 (ΔE 15.1), TH Navy 5909 (ΔE 15.1), Nautical Teal 9076 (ΔE 15.0), Poker Primrose 9011 (ΔE 14.8), Mint 5538 (ΔE 14.5). 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.
