Sturdy Sash Ruby

#d51450
Notes

Sturdy Sash Ruby (#D51450) 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 (341°, 83%, 46%) 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

Sturdy
adjective

Old French estourdi, stunned, reckless — drifted in English to mean robust, well-built. Used as a color modifier since the seventeenth century for hues that read as durable and unfussy — the working browns of saddle leather, the working greens of pasture wool. Sits in the bold-and-warm corner alongside robust and solid.

Sash
modifier

Arabic shāsh, muslin-strip-or-turban-cloth. As a color modifier, sash implies a wound-strip-and-cummerbund-and-bandolier quality, the visual register of Mughal-cummerbund-and-Spanish-fajín-sash hand-wound-strip-and-cummerbund-and-bandolier Mughal-cummerbund-and-Spanish-fajín-sash-and-Ottoman-sash sash-and-wound-strip-and-cummerbund surfaces under Mughal-cummerbund-and-Spanish-fajín-sash-and-Ottoman-sash Mughal-Delhi-and-Iberian-and-Ottoman-Topkapi wound-cloth-light. Sits at the modifier-and-textile end of the grid, parallel to kilt and shawl in usage.

Ruby
noun

From the Latin ruber — simply, red. The gemstone is a chromium-tinged corundum, harder than anything in nature except diamond, and so saturated that a fine Burmese pigeon's blood ruby at auction outpaces a comparable diamond by weight. The color borrows the gem's confidence: a clear, glassy red without the brown of garnet or the blue of crimson.

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.
