Combustive Santolina

#03f0dd
Notes

Combustive Santolina (#03F0DD) is a true cyan 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 (175°, 98%, 48%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

As a color modifier, combustive implies a saturated-and-burning-active quality, the bright color of blast-furnace-and-foundry combustion-chamber emission. Sits at the bright-and-warm end of the grid, parallel to fiery and blazing in usage.

Santolina
noun

The genus Santolina — Mediterranean cotton-lavender, dry-garden silver-foliage shrubs commonly clipped into low formal hedges. The color refers to mature S. chamaecyparissus foliage: a soft, slightly cool gray-green with the matte velvet finish of needle-shaped silver leaves. Drier than artemisia.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
