Luminous Persimmon
Luminous Persimmon (#F75611) is a true orange 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 (18°, 93%, 52%) 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
Latin lūminōsus, full of light — adjectival suffix -ous, derived from lūmen (light). As a color modifier, luminous implies a saturated-and-light-emitting quality where the hue carries internal-glow visual register. Sits at the bright-and-saturated end of the grid, parallel to radiant and resplendent in usage.
Diospyros kaki, the East Asian persimmon — a fruit eaten ripe from the tree in Japan since at least the eighth century, where its color is named kaki-iro. The fall color of the unblemished astringent fruit: a dense, slightly red orange with the velvet finish of a wax-skinned Hachiya. Closer to maple syrup than to citrus, with the patient warmth of a fruit that takes a hard frost to sweeten.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
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.
