Strong Persimmon

#e15105
Notes

Strong Persimmon (#E15105) 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 (21°, 96%, 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Strong
adjective

Old English strang, firm, vigorous — applied to color since the sixteenth century. Strong red, strong tea: a color at full strength is the maximum saturation the medium can produce. Sits at the saturated mid corner of the grid, parallel to bold in usage but slightly more focused on pigment density than on assertion.

Persimmon
noun

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.
