Starched Dusk

#8b360a
Notes

Starched Dusk (#8B360A) is a deep 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 (20°, 87%, 29%) places it in the highly saturated band at a dark 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

Starched
adjective

Old English stercan, to stiffen — past-participle of starch. As a color modifier, starched implies a clear-and-stiff-and-formal quality, the crisp color of Edwardian-period formal-evening-shirt-and-collar starched-and-pressed dress-attire. Sits at the crisp-and-finished end of the grid, parallel to pressed and ironed in usage.

Dusk
noun

The transitional sky color in the half-hour after sunset — when the upper atmosphere still scatters reds and oranges off the horizon. Dusk as an orange color refers to the warm horizon glow at civil twilight: a soft, slightly muted deep orange-red with the optical complexity of forward-scattered light. Cooler than sunset, deeper than ember.
