Buttressed Drosera

#cb3e9a
Notes

Buttressed Drosera (#CB3E9A) is a true magenta 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 (321°, 58%, 52%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Buttressed
adjective

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.

Drosera
noun

Cosmopolitan sundew genus — particularly the Drosera capensis (Cape sundew) whose deep-magenta glandular-tentacle-tipped leaves are coated in iridescent dewdrops that capture insect prey. Drosera color refers to a fully developed Drosera capensis glandular-leaf in raking light: a saturated, slightly cool deep magenta with the iridescent satin finish of glandular-tentacle dewdrops against pigmented leaf substrate. The Greek droserós means dewy.
