Forceful Brittany
Forceful Brittany (#469B0A) is a deep lime 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 (95°, 88%, 32%) places it in the highly saturated band at a dark 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old French force, strength — adjectival suffix -ful. As a color modifier, forceful implies a saturated-and-vigorous quality where the hue exerts visual force on its substrate. Sits at the bold-and-saturated end of the grid, parallel to mighty and commanding in tone.
The Celtic French peninsula — and the saturated green of Breton hillsides, triskel embroidery, and the Bretagne verte (green Brittany) of inland farmland. Brittany refers to a Breton hillside in spring: a saturated, slightly cool deep green with the matte finish of high-rainfall Atlantic pasture.
