Pressed Tideway

#54edfd
Notes

Pressed Tideway (#54EDFD) is a true cyan 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 (186°, 98%, 66%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

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.

Tideway
noun

A tidal river channel — particularly the tidal Thames between London Bridge and Teddington Lock, the historical Tideway of London's Thames-side commerce. Tideway color refers to mid-tide Thames at Greenwich on a clear day: a soft, slightly cool deep blue-green with the optical complexity of tidal-mixed brackish water.
