Rousing Oregano

#81ba35
Notes

Rousing Oregano (#81BA35) is a true lime with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (86°, 56%, 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

Rousing
adjective

Old English rūsan, to rush — present-participle of rouse. As a color modifier, rousing implies a saturated-and-wakening-and-active quality, the bright color of dawn-chorus-and-morning-bell atmospheric-and-aural stimulation. Sits at the bright-and-active end of the grid, parallel to awakening and invigorating in usage.

Oregano
noun

Origanum vulgare, the Mediterranean herb essential to Italian and Greek cooking — pizza, salsa pomodoro, Greek salad dressings. The color refers to fresh oregano sprigs in a Greek kitchen: a saturated, slightly muted yellow-green with the matte finish of small clustered mint-family leaves.
