Grounded Float Ruby

#98181e
Notes

Grounded Float Ruby (#98181E) 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 (357°, 73%, 35%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Grounded
adjective

Old English grund, bottom / foundation — past-participle of ground. As a color modifier, grounded implies a saturated-and-foundational quality where the hue anchors the surrounding palette through its weighty presence. Sits at the bold-and-balanced end of the grid, parallel to centered and anchored.

Float
modifier

Old English flotian, to-move-on-water-surface. As a color modifier, float implies a buoyant-and-untethered-and-drifting quality, the visual register of lotus-pond-and-petal-on-river-float hand-buoyant-and-untethered-and-drifting lotus-pond-and-petal-on-river-and-paper-lantern floated-and-buoyant-and-untethered-and-drifting surfaces under lotus-pond-and-petal-on-river-and-paper-lantern Heian-and-Edo-and-Yangtze still-water-light. Sits at the modifier-and-mood end of the grid, parallel to drift and hover 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.

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.
