Punchy Jupiter Crimson

#fc5178
Notes

Punchy Jupiter Crimson (#FC5178) is a true red 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 (346°, 97%, 65%) 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 teal. 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.

Jupiter
modifier

Latin Iuppiter, Roman-king-of-gods-and-fifth-planet. As a color modifier, jupiter implies a Roman-king-of-gods-and-fifth-planet-and-gas-giant quality, the visual register of Roman-Jupiter-Optimus-Maximus-and-Galileo-moons hand-Roman-king-of-gods-and-fifth-planet-and-gas-giant Roman-Jupiter-Optimus-Maximus-and-Galileo-moons-and-Great-Red-Spot jupiter-and-Roman-king-of-gods surfaces under Roman-Jupiter-Optimus-Maximus-and-Galileo-moons-and-Great-Red-Spot Capitoline-Hill-and-Galilean-moon-discovery king-of-planets-light. Sits at the modifier-and-zodiac end of the grid, parallel to venus and saturn in usage.

Crimson
noun

From the Old Spanish cremesin, itself from the Arabic qirmiz — the kermes scale insect, dried and ground into a brilliant carmine dye prized in the medieval Mediterranean. For centuries the most expensive red on a draper's shelf, reserved for cardinals, kings, and the cloth that gave English the word crimson. Cooler than scarlet, deeper than rose; the color of pomegranate seeds and a serious occasion.

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.
