Homespun Sumirenezu

#0a1522
Notes

Homespun Sumirenezu (#0A1522) is a deep azure with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (213°, 55%, 9%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Sits at the neutral-and-traditional end of the grid, parallel to folksy and homey in usage.

Sumirenezu
