Weighty Cope Ruby

#9b191a
Notes

Weighty Cope Ruby (#9B191A) 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 (360°, 72%, 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

Weighty
adjective

Old English wegan, to weigh — adjectival suffix -y. As a color modifier, weighty implies a saturated-and-heavy-and-imposing quality where the hue carries visual mass and gravitational presence. Sits at the bold-and-weighty end of the grid, parallel to substantial and hefty in usage.

Cope
modifier

Latin cappa, long-ecclesiastical-cloak. As a color modifier, cope implies a long-ecclesiastical-cloak-and-bishop's-cope quality, the visual register of Anglican-and-Catholic-bishop's-cope hand-long-ecclesiastical-cloak-and-bishop's-cope Anglican-and-Catholic-bishop's-cope-and-Westminster-and-Vatican cope-and-long-ecclesiastical-cloak surfaces under Anglican-and-Catholic-bishop's-cope-and-Westminster-and-Vatican Westminster-Abbey-and-Sistine-Chapel ecclesiastical-cloak-light. Sits at the modifier-and-textile end of the grid, parallel to cloak and cape 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.
