Tidy Lobelia

#4cdcdb
Notes

Tidy Lobelia (#4CDCDB) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (180°, 67%, 58%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Tidy
adjective

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.

Lobelia
noun

The genus Lobelia — particularly L. erinus, the common cottage-garden annual with cascading deep-blue flowers. The color refers to a fresh L. erinus in midsummer: a saturated, slightly cool deep blue with the satin finish of small bilateral flowers. Cooler than borage.
