Bold Nebula Brick

#983922
Notes

Bold Nebula Brick (#983922) 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 (12°, 63%, 36%) 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

Bold
adjective

Old English beald, brave, courageous — a quality word that crossed over to color in the late seventeenth century. Bold describes a color that asserts itself: high saturation combined with mid lightness, where the hue presents itself without compromise. Sits at the center of the bold-bucket grid, near strong and rich. Closer to a presence word than a pigment word.

Nebula
modifier

Latin nebula, mist-or-cloud. As a color modifier, nebula implies a glowing-cloud-and-stellar-cradle quality, the visual register of Orion-and-Eagle-Nebula hand-glowing-cloud-and-stellar-cradle Orion-and-Eagle-and-Crab-Nebula nebula-and-glowing-cloud-and-stellar-cradle surfaces under Orion-and-Eagle-and-Crab-Nebula Hubble-and-James-Webb-deep-field stellar-cradle-light. Sits at the modifier-and-cosmic end of the grid, parallel to plasma and meteor in usage.

Brick
noun

Fired clay, mineral red. The color refers to common building brick — iron-rich earthenware kilned to the specific dusky red-orange of a Victorian terrace, a Roman aqueduct, an adobe wall in New Mexico. Less saturated than ruby, warmer than burgundy, with a chalky cast that reads as architectural rather than decorative.

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.

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.
