Buttressed Bee-eater

#178e4d
Notes

Buttressed Bee-eater (#178E4D) is a deep teal with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (147°, 72%, 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Old French bouterez, thrusting-mass — past-participle of buttress, derived from bouter (to thrust). As a color modifier, buttressed implies a saturated-and-architecturally-supported quality, the deep-rich color of Gothic-Cathedral flying-buttress-and-rib-vault stone-architecture. Sits at the bold-and-fortified end of the grid, parallel to fortified and reinforced.

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.
