Resolute Hong

#ca2318
Notes

Resolute Hong (#CA2318) 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 (4°, 79%, 44%) places it in the highly saturated band at a mid 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

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.

Hong
noun

The fundamental Chinese word for red — and the cultural color of weddings, festivals, lacquerware, and prosperity across thousands of years of Han through modern use. The color refers to zhongguohong (China red) — the saturated lacquer red of imperial palaces and bridal sashes: a saturated, slightly orange-shifted deep red with the high gloss of lacquer. Brighter than crimson, deeper than vermillion.
