DMC 504 to Cosmo: Thread Conversion

Cosmo 894 is a close match, but the caution is meaningful here: at pale values, the eye is more sensitive to small hue shifts than at deep colors. A pale blue-green that shifts even slightly toward pure blue or pure green reads as a different color. Test Cosmo 894 on your actual project fabric (not just a white thread card) before using it in large pale fills, since the fabric color significantly influences how barely-there threads appear in context.
