Defined Lithodora

#2bada8
Notes

Defined Lithodora (#2BADA8) 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 (178°, 60%, 42%) 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

Defined
adjective

Latin dēfīnīre, to set bounds — past-participle of define. As a color modifier, defined implies a clear-and-edge-distinct-and-precise quality where the hue carries the visual register of sharp-bounded-and-clearly-delimited surface. Sits at the crisp-and-clear end of the grid, parallel to crisp and sharp in usage.

Lithodora
noun

The genus Lithodora — Mediterranean rock-garden ground covers with intensely deep-blue flowers. L. diffusa 'Heavenly Blue' is among the most saturated blue flowers grown in temperate gardens. The color refers to a fresh L. diffusa mat in flower: a saturated, slightly cool deep blue with the matte finish of small five-petaled flower.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
