U+7E90 "纐" CJK Unified Ideograph-# Unicode Character

U+7E90 "纐" CJK Unified Ideograph-# is a rare Chinese character that primarily appears in Japanese kanji, where it is read as "kō" and refers to a type of dyeing technique involving the tying and resist-dyeing of fabric, similar to shibori or tie-dye, though it can also mean "scarlet" or "crimson" in some contexts. Its structure combines the silk radical on the left with a phonetic component on the right, reflecting its textile-related meaning. This character is not commonly used in everyday modern Chinese or Japanese writing, but it appears in specialized historical or artistic discussions of dyeing processes.
