Commanding Scarlet
Commanding Scarlet (#9A1406) 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 (6°, 93%, 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin commendāre, to entrust / order — present-participle of command. As a color modifier, commanding implies a saturated-and-authoritative quality where the hue claims visual leadership of its surrounding palette. Sits at the bold-and-authoritative end of the grid, parallel to authoritative and imperial in usage.
From the medieval Latin scarlatum, originally a fine wool cloth rather than a color — the dye came later when the fabric was associated with the bright red of kermes-stained textiles. The defining red of British military uniforms, fox-hunt coats, and The Scarlet Letter. Hotter than crimson, less orange than vermillion: a pure, attention-demanding red.
