Mighty Adonis

#c63b1f
Notes

Mighty Adonis (#C63B1F) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (10°, 73%, 45%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Mighty
adjective

Old English mihtig, strong — adjectival suffix -y, sharing root with German mächtig. As a color modifier, mighty implies a saturated-and-strong-presence quality, where the hue commands visual attention through pure pigmentation strength. Sits at the bold-and-saturated end of the grid, parallel to forceful and commanding in tone.

Adonis
noun

Adonis annua, the small wild buttercup of European meadows — also called pheasant's eye — with single deep red flowers and dark centers. Named for the Greek mythological youth whose blood, in Ovid's telling, sprouted the flower. The color refers to a fresh Adonis bloom in late spring: a saturated, slightly cool deep red with the matte finish of a six-petaled wild flower. Deeper than coral.
