Bold Trafalgar

#074399
Notes

Bold Trafalgar (#074399) is a deep azure 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 (215°, 91%, 31%) 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 amber. 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.

Trafalgar
noun

The Cape Trafalgar headland off southern Spain — site of the 1805 Battle of Trafalgar (Nelson's decisive naval victory over Napoleon's fleet). Trafalgar color refers to the deep blue of HMS Victory's preserved hull paint at Portsmouth: a saturated, slightly cool deep blue with the matte finish of period-correct marine paint.

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.
