Pressed Uguisu

#4f7c21
Notes

Pressed Uguisu (#4F7C21) is a deep lime with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (90°, 58%, 31%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Pressed
adjective

Latin pressāre, to press — past-participle of press. As a color modifier, pressed implies a clear-and-smoothed-and-flattened quality, the crisp color of Mid-Century-Modern freshly-pressed-shirt-and-trouser ironed-textile finish. Sits at the crisp-and-finished end of the grid, parallel to ironed and starched in usage.

Uguisu
noun

Horornis diphone, the Japanese bush warbler — and the slightly muted olive-yellow of the bird's plumage. Uguisu-iro is a traditional Japanese color used in tea-ceremony pottery and fukusa silk wraps. The color refers to a fresh-molted bush warbler: a soft, slightly muted yellow-green with the matte finish of small bird feathers. Cooler than wakaba.
