Lambent Heather

#c168ea
Notes

Lambent Heather (#C168EA) is a true violet with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (281°, 76%, 66%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Lambent
adjective

Latin lambēns, licking-lightly — present-participle of lambere (to lick). As a color modifier, lambent implies a saturated-and-soft-flickering quality, the bright color of candle-flame-and-firefly gentle-flickering light-emission against the surrounding darkness. Sits at the bright-and-soft end of the grid, parallel to glimmering and flickering in usage.

Heather
noun

Calluna vulgaris, the dominant ground cover of Scottish, Irish, and northern English moorland — the small woody shrub whose pink-purple flower spikes color hill country in late summer. The color refers to mature heather in August bloom: a soft, slightly muted pale purple-pink with the matte finish of small clustered flowers covering an entire moor at scale. Lighter than mauve, warmer than lavender, with the moorland weight of a plant whose name names a landscape.

Wide gamut

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
