Tidy Lemon
Tidy Lemon (#99A945) is a true yellow with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (70°, 42%, 47%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English tidig, timely — drifted in modern English to mean neat, orderly. Used as a color modifier for hues that read as composed and unfussy. Tidy beige, tidy gray: moderate saturation combined with optical neatness. Sits at the crisp-bucket alongside plain and modest.
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.
