Resilient Balm Ruby

#a31c20
Notes

Resilient Balm Ruby (#A31C20) 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 (358°, 71%, 37%) 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

Resilient
adjective

Latin resiliēns, springing-back — present-participle of resilīre. As a color modifier, resilient implies a saturated-and-recovering-and-flexible quality where the hue maintains its strength under visual pressure. Sits at the bold-and-resilient end of the grid, parallel to tough and hardy in usage.

Balm
modifier

Latin balsamum, aromatic-resin-and-soothing-oil. As a color modifier, balm implies an aromatic-resin-and-soothing-oil-and-lemon-balm quality, the visual register of apothecary-balm-and-lemon-balm hand-aromatic-resin-and-soothing-oil-and-lemon-balm apothecary-balm-and-lemon-balm-and-Tudor-still-room balm-and-aromatic-resin-and-soothing-oil surfaces under apothecary-balm-and-lemon-balm-and-Tudor-still-room Tudor-still-room-and-monastic-physic-garden apothecary-and-still-room-light. Sits at the modifier-and-flavor end of the grid, parallel to bergamot and hyssop 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.
