Ironed Lemon

#5b6a09
Notes

Ironed Lemon (#5B6A09) is a deep yellow 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 (69°, 84%, 23%) 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Ironed
adjective

Old English īsern, iron — past-participle of iron. As a color modifier, ironed implies a clear-and-smoothed-and-pressed quality, the crisp color of Mid-Century-Modern freshly-ironed-shirt-and-trouser dress-attire textile finish. Sits at the crisp-and-finished end of the grid, parallel to pressed and starched in usage.

Lemon
noun

Citrus limon, the cultivated yellow citrus of southern Italian and North African groves. Originally a hybrid of citron and bitter orange, the lemon spread through the Mediterranean during the medieval Arab agricultural revolution. The color refers to the skin of a ripe Eureka lemon: a clean, slightly green-shifted yellow with the matte finish of citrus rind. The fruit's acidity gave English the figurative lemon — something that disappoints — separately from the color.
