Rugged Persimmon
Rugged Persimmon (#E9570F) 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 (20°, 88%, 49%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old Norse rugga, rough / coarse — adjectival suffix -ed. As a color modifier, rugged implies a saturated-and-rough-and-weathered quality, the deep-rich color of Scottish-Highlands-and-Norwegian-fjord outdoor-and-mountain landscape. Sits at the bold-and-weathered end of the grid, parallel to tough and sinewy 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.

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.
