DMC 807 to Cosmo: Thread Conversion

Cosmo 374 is a close match for DMC 807 Peacock Blue. Peacock blue is one of the more variable color families across brands because it sits at the intersection of blue and green — small formulation differences pull the color noticeably in one direction or the other, and close-rated substitutes at this balanced teal position have more room to drift than they would in a more unambiguously blue or green color. For bohemian and Moroccan-inspired designs where the turquoise-blue vibrancy is a key palette element — where 807 establishes the specific bright, saturated blue-turquoise quality of North African ceramic tiles and textiles — testing Cosmo 374 in your design context before large-area use is particularly worthwhile. The essential test is whether Cosmo 374 reads as the same vivid, slightly blue-dominant teal or as a slightly greener aqua. Cosmo’s silky thread finish can give teal colors a particularly luminous, jewel-like quality in display conditions — a potential advantage for mermaid and tropical pieces where vibrancy is desirable, but worth evaluating against your other palette threads to confirm the sheen difference doesn’t create a texture inconsistency if mixing Cosmo with DMC in the same design. For small accent and petal highlight use, the close match is workable without extensive testing.
