Rousing Marjoram

#66a438
Notes

Rousing Marjoram (#66A438) is a true lime 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 (94°, 49%, 43%) 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.

Marjoram
noun

Origanum majorana, the Mediterranean culinary herb related to oregano — sweeter, milder, used in French Provence herb mixes and traditional Roman sausages. The color refers to fresh-picked marjoram leaves: a soft, slightly muted yellow-green with the matte finish of small mint-family leaves. Cooler than oregano.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
