Ironed Cyaneus

#356c6b
Notes

Ironed Cyaneus (#356C6B) is a deep 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 (179°, 34%, 32%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Ironed
adjective

Old English īsern, iron — past-participle of iron. As a color modifier, ironed implies a clear-and-smoothed-and-pressed quality, the crisp color of Mid-Century-Modern freshly-ironed-shirt-and-trouser dress-attire textile finish. Sits at the crisp-and-finished end of the grid, parallel to pressed and starched 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.
