Plentiful Royal
Plentiful Royal (#4D73EB) is a true blue with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (226°, 80%, 61%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old French plentif, abundant — adjectival suffix -ful, derived from Latin plēnitās (fullness). As a color modifier, plentiful implies a saturated-and-generous quality where the hue carries rich visual abundance without restraint. Sits at the bold-and-saturated end of the grid, parallel to abundant and bountiful.
The blue of European royal court dress and regalia from the late seventeenth century forward — the color of British peers' robes, French royal sashes, the lining of the crown-jewel cases. The color refers to a saturated, slightly violet-shifted blue with the matte finish of velvet or melton wool dyed to maximum intensity: deeper than cornflower, warmer than ultramarine, with the heraldic weight of a color reserved for monarchs and the official Crown.
