Brimming Geranium

#c04138
Notes

Brimming Geranium (#C04138) is a true red with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (4°, 55%, 49%) 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

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.

Geranium
noun

The genus Pelargonium (commonly called geraniums in English horticulture) — particularly P. zonale and P. peltatum, the bright red-flowered geraniums of European balconies and hanging baskets. The color refers to a fresh red geranium bloom in summer: a saturated, slightly orange red with the matte finish of small clustered five-petaled flowers. Brighter than scarlet, warmer than tomato.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
