Resolute Carmesí

#d52d2b
Notes

Resolute Carmesí (#D52D2B) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (1°, 67%, 50%) 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

Resolute
adjective

From the Latin resolutus, unwavering — used as a color modifier in literary contexts for hues that read as committed and unmoving. Resolute blue, resolute green: the saturation is full, the hue holds its position without shifting under different light. Sits in the bold-bucket center alongside strong and true, with slightly more focus on stability than presence.

Carmesí
noun

The Spanish word for crimson — borrowed via Arabic qirmiz (the kermes scale insect) and used in the deep red textiles of medieval Castilian and Valencian silk. The color refers to a carmesí-dyed Castilian silk: a saturated, slightly cool deep red with the satin finish of plant-and-insect dye. The Spanish cousin of crimson, slightly more formal in register.
