Throbbing Tangerine

#ee8901
Notes

Throbbing Tangerine (#EE8901) 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 (34°, 99%, 47%) 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

Throbbing
adjective

Imitative-onomatopoeic origin — present-participle of throb, with sound-and-action mimicry. As a color modifier, throbbing implies a saturated-and-pulsing-and-resonant quality, the bright color of bass-drop-and-rave-light low-frequency rhythm-pulse emission. Sits at the bright-and-active end of the grid, parallel to pulsating and strobing in usage.

Tangerine
noun

Named for the city of Tangier in Morocco, the port through which this small mandarin variety reached Europe in the early nineteenth century. The color refers to the skin of a fully ripe tangerine: a saturated, slightly red-shifted orange that's warmer than apricot and brighter than rust. The pigment is the same beta-carotene that colors carrots and pumpkins, just at higher concentration on the rind.
