Mighty Lace Ruby
Mighty Lace Ruby (#931617) is a deep 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 (360°, 74%, 33%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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
Old English mihtig, strong — adjectival suffix -y, sharing root with German mächtig. As a color modifier, mighty implies a saturated-and-strong-presence quality, where the hue commands visual attention through pure pigmentation strength. Sits at the bold-and-saturated end of the grid, parallel to forceful and commanding in tone.
Old French laz, cord / lace. As a color modifier, lace implies a hand-tatted-and-decorative-net quality, the visual register of Edwardian-and-Belgian-Bruges-lace hand-tatted-and-bobbin-lace bridal-and-formal-wear delicate-network-pattern textile surfaces under Bruges-and-Edwardian hand-tatted-lace filtered light. Sits at the modifier-and-texture end of the grid, parallel to silk and fluff in usage.
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.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
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
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.
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.
