Saturated Spar Rose

#b6153a
Notes

Saturated Spar Rose (#B6153A) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (346°, 79%, 40%) 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

Saturated
adjective

From the Latin saturatus, past participle of saturare, to fill. A technical color term in modern usage — saturation is one of the three axes of HSL (with hue and lightness). As a modifier, saturated implies that the hue is at or near its maximum chromatic intensity. Sits at the bold-and-bright top of the grid.

Spar
modifier

Old Norse sparri, long-pole. As a color modifier, spar implies a long-wooden-pole-for-sail quality, the visual register of Tall-Ship-and-Royal-Navy-spar hand-cut long-wooden-pole-and-spar-for-sail mast-and-yard-and-boom maritime-rigging surfaces under tall-ship-spar-and-yard maritime-rigging light. Sits at the modifier-and-nautical end of the grid, parallel to mast and boom 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.

WCAG contrast

The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.

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.
