Effective Mojito

#405f03
Notes

Effective Mojito (#405F03) is a deep lime 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 (80°, 94%, 19%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Mojito
noun

The Cuban cocktail of rum, lime, mint, sugar, and soda — popularized by Hemingway in Old Man and the Sea settings. Mojito color refers to a fresh-shaken mojito with crushed mint: a soft, slightly cool yellow-green with the optical clarity of muddled-herb-and-spirits.
