Reinforced Watermelon

#aa1791
Notes

Reinforced Watermelon (#AA1791) is a true magenta 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 (310°, 76%, 38%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Reinforced
adjective

Latin re- plus inforce — past-participle of reinforce. As a color modifier, reinforced implies a saturated-and-doubled-up-and-strengthened quality where the hue carries layered pigmentation for maximum visual presence. Sits at the bold-and-fortified end of the grid, parallel to fortified and buttressed.

Watermelon
noun

Citrullus lanatus, the African cucurbit cultivated for at least four thousand years for its high-water-content red flesh. The color refers to the cross-section of a ripe watermelon's interior: a saturated, slightly cool deep pink-red with the optical brightness of high-water-content fruit pigmented by lycopene. Cooler than coral, warmer than salmon, with the summer-cookout weight of a fruit that gives English a synonym for unripe-pink.

Wide gamut

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
