Hemmed Cyaneus

#478b95
Notes

Hemmed Cyaneus (#478B95) is a true cyan 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 (188°, 35%, 43%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Hemmed
adjective

Old English hem, border — past-participle of hem. As a color modifier, hemmed implies a clear-and-finished-and-bordered quality where the hue carries the visual register of carefully-hemmed-and-finished textile-edge. Sits at the crisp-and-finished end of the grid, parallel to trim and finished in usage.

Cyaneus
noun

The Latin word for deep blue — used in Roman texts for the blue of cornflower (Centaurea cyanus) and the saturated blue of imperial-banquet kingfisher feathers. The color refers to a Roman-period kingfisher mosaic: a saturated, slightly cool deep blue with the matte finish of tessera-set glass mosaic.
