The Isacord pairing is Amann USA's official Madeira Polyneon to Isacord cross-reference. The Candle Thread pairing is the conversion sheet Candle Thread USA sent on August 26, 2026, and the Candle color dot is the value from their own master shade card. The Madeira dot is measured off Madeira's own spool photograph, not a digitized chart. Search the whole charts in either direction on the Polyneon to Isacord converter and the Madeira to Candle Thread converter.
Amann's own Madeira Polyneon to Isacord chart lists Isacord 1233 for Polyneon 1857. Some pairings on that chart are exact and the rest are the nearest available color, so a test stitch is the final word.
Candle Thread USA's own conversion chart lists Candle 8697 for Polyneon 1857, and marks it their top match grade. That is the maker's claim about their own thread, not an independent measurement.
No. Screens are backlit and dye lots move a little between runs. The dots here are for recognizing a color, not approving one. For a logo color, or anything a customer will hold against a brand guide, stitch a test and look at it in daylight.
