Rousing Calendula

#fb5f23
Notes

Rousing Calendula (#FB5F23) 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 (17°, 96%, 56%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Rousing
adjective

Old English rūsan, to rush — present-participle of rouse. As a color modifier, rousing implies a saturated-and-wakening-and-active quality, the bright color of dawn-chorus-and-morning-bell atmospheric-and-aural stimulation. Sits at the bright-and-active end of the grid, parallel to awakening and invigorating in usage.

Calendula
noun

Calendula officinalis, the pot marigold of medieval European herbal gardens — used as a saffron substitute in Renaissance kitchens and as a wound-healing salve in Victorian apothecaries. The color refers to a fully open Calendula flower: a saturated, slightly red yellow-orange with the matte finish of small ray-florets. Cooler than marigold, brighter than goldenrod.

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.
