Rich Lux Strawberry
Rich Lux Strawberry (#D4102B) is a true red with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (352°, 86%, 45%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old French riche, wealthy, abundant — applied to color since the medieval period for hues that read as plentiful in pigment. Rich red, rich brown: the implication is depth combined with saturation, a color that gives the eye more to absorb. Sits at the saturated mid-light corner of the engine's grid, slightly warmer than bold and deeper than vivid.
Latin lux, light. As a color modifier, lux implies a Latin-light-and-Fiat-Lux-and-Lux-Aeterna quality, the visual register of Genesis-Fiat-Lux-and-Lux-Aeterna hand-Latin-light-and-Fiat-Lux-and-Lux-Aeterna Genesis-Fiat-Lux-and-Lux-Aeterna-and-Requiem-mass lux-and-Latin-light-and-Fiat-Lux surfaces under Genesis-Fiat-Lux-and-Lux-Aeterna-and-Requiem-mass Vulgate-and-Tridentine-Mass primal-light. Sits at the modifier-and-Latin end of the grid, parallel to ignis and opus in usage.
Fragaria × ananassa, the cultivated strawberry of European gardens since the eighteenth century. The color refers to the surface of a ripe berry: a clean, bright red with a slight blue shift in the shadows of the achenes. Warmer than ruby, lighter than crimson, with the optical brightness of fresh fruit rather than the depth of pigment or gem.
