Radiant Coral
Radiant Coral (#F58B4B) 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 (23°, 89%, 63%) 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
From the Latin radiare, to emit rays — used as a color word since the seventeenth century for hues that read as luminous and emitting. Radiant gold, radiant pink: the implication is high luminance combined with the optical impression of an outward light. Sits in the bright-bucket center alongside glowing.
Mediterranean Corallium rubrum — the red coral of antiquity, harvested from rocky reefs off Sardinia and North Africa for amulets, beads, and the lacquered ornaments that signaled wealth in Etruscan, Roman, and Tibetan culture alike. The color sits between rose and orange, warmer than salmon, softer than vermillion. A reef color and a flesh color at once.

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.
