Modest Bee-eater

#21cfc7
Notes

Modest Bee-eater (#21CFC7) 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 (177°, 73%, 47%) 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

Modest
adjective

Latin modestus, moderate — used as a color modifier since the sixteenth century for hues that read as understated and unwilling to claim more visual space than they need. Modest taupe, modest beige: moderate-to-low saturation combined with optical restraint. Sits at the crisp-and-quiet edge of the grid alongside quiet and plain.

Bee-eater
noun

The family Meropidae — Old World bee-eaters whose males display saturated blue-green plumage with chestnut and yellow markings. The color refers to a male European bee-eater's wing: a saturated, slightly cool deep blue-green with the iridescent satin finish of structurally colored feathers.
