Composed Vela Rose

#b50b34
Notes

Composed Vela Rose (#B50B34) is a true red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (346°, 89%, 38%) 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

Composed
adjective

The past participle of compose, to arrange together — used as a color modifier for hues that read as deliberate and balanced. Composed black, composed gray: the saturation is moderate, the hue is calmly positioned without aggression. Sits at the bold-and-quiet edge of the grid near settled and resolute.

Vela
modifier

Latin vela, sails-of-the-Argo. As a color modifier, vela implies a southern-hemisphere-and-Argo-sail-and-supernova-remnant quality, the visual register of Vela-supernova-remnant-and-Argo-sails hand-southern-hemisphere-and-Argo-sail-and-supernova-remnant Vela-supernova-remnant-and-Argo-sails-and-southern-Milky-Way vela-and-southern-hemisphere-and-Argo-sail surfaces under Vela-supernova-remnant-and-Argo-sails-and-southern-Milky-Way Southern-Cross-and-southern-zenith southern-stellar-light. Sits at the modifier-and-cosmic end of the grid, parallel to cygnus and draco in usage.

Rose
noun

The Latin rosa, the Greek rhodon, the Persian gul — every European language has a different name for the same flower and the same color. Rose covers the spectrum from blush to fuchsia depending on the cultivar, but in pigment shorthand it means a cool, slightly bluish red — the inside of a damask petal, the dye that washes out of madder root.

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.
