Rich Tigerlily

#b73c0d
Notes

Rich Tigerlily (#B73C0D) is a true orange 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 (17°, 87%, 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Rich
adjective

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.

Tigerlily
noun

Lilium lancifolium, the East Asian lily named for the dark-spotted orange petals that suggested big-cat markings to Victorian gardeners. The color is the petal interior of a fully open tigerlily: a saturated, slightly red orange with the matte finish of bee-pollinated flower. Warmer than carrot, more chromatic than rust; the orange of a high-summer perennial bed.

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.
