Bold Merlot

#a62503
Notes

Bold Merlot (#A62503) 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 (13°, 96%, 33%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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.

Merlot
noun

A Bordeaux red-wine grape — softer, fruitier, earlier-ripening than Cabernet Sauvignon, and the most-planted red grape in France. The color refers to a young Merlot from Saint-Émilion in a glass: a saturated, slightly cool deep red with the optical clarity of mid-tannin wine. Lighter than Cabernet, warmer than Pinot.

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.
