Japanese Color Atlas日本色譜Before there were hexes, there were robes. Heian-period women layered up to twelve silks; what you read as a single “color name” was actually the edge of two — outer silk over inner silk, seen at the sleeve.
“white over red — petals against sky”
“deep crimson over pale pink — plum branch”
“kerria yellow over red — riverbank flowers”
“spring green over red — new shoots”
“pine green over purple — winter pine”
“purple over pale lilac — ripe grape”
“decayed brown over dark red — late autumn”
“white over moss — snow over moss”
Because the Heian eye saw the relationship. A single bolt of silk had a color. A robe — twelve silks layered, sleeves trailing across the floor — had a season.
