Brimming Plectranthus

#1770e0
Notes

Brimming Plectranthus (#1770E0) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (213°, 81%, 48%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Brimming
adjective

Old English brymme, brim / edge — present-participle of brim. As a color modifier, brimming implies a saturated-and-overflowing quality where the hue spills past the edge of its visual container with rich pigmentation. Sits at the bold-and-saturated end of the grid, parallel to replete and abundant.

Plectranthus
noun

The genus Plectranthus — particularly P. ecklonii, the South African blue spur flower whose fall-blooming blue flower spikes attract sunbirds. The color refers to a fresh P. ecklonii at peak autumn bloom: a saturated, slightly cool deep blue-violet with the matte finish of small clustered mint-family flowers.
