Pressed Cyan

#40c8df
Notes

Pressed Cyan (#40C8DF) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (189°, 71%, 56%) 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

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.

Cyan
noun

From the Greek kyanos, deep blue, originally referring to the lapis-derived blue of antiquity. In modern usage, cyan is one of the four printing primaries (with magenta, yellow, and black) and an additive primary on screens. The color refers to a pure CMYK cyan tile: a saturated, clean blue-green with the optical brightness of an additive-color primary. Cooler than turquoise, lighter than cerulean, with the technical specificity of a color defined by a printing-press standard.
