Punchy Echium

#15ccf7
Notes

Punchy Echium (#15CCF7) 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 (191°, 93%, 53%) 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.

Etymology

Punchy
adjective

A modern adjectival form of punch, to strike sharply. Used as a color word since the early twentieth century for hues that read as highly contrasting and visually loud. Punchy red, punchy yellow: the implication is full saturation combined with optical impact. Sits across the bold and bright buckets, near vivid and striking.

Echium
noun

The genus Echium — Mediterranean and Macaronesian biennials with tall deep-blue flower spikes. E. vulgare (viper's bugloss) covers European chalk grasslands; E. wildpretii of Tenerife produces three-meter spires. The color refers to fresh E. vulgare in flower: a saturated, slightly cool deep blue-violet.

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.
