Bright Juniper

#66c257
Notes

Bright Juniper (#66C257) is a true green 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 (112°, 47%, 55%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Bright
adjective

Old English beorht, shining, luminous — cognate with the German Bracht, splendor. Applied to color since at least the medieval period for hues that read as luminous: not just light in value but optically active, as if scattering more light back than a dimmer color of the same lightness would. Sits at the bright-bucket center alongside vivid and brilliant.

Juniper
noun

The genus Juniperus, evergreen shrubs and trees whose fleshy berries — actually fleshy cones — flavor gin and Scandinavian sauerkraut. The color refers to the foliage of a mature juniper: a deep, slightly muted green with the matte finish of scale leaves and resinous waxes. Drabber than spruce, warmer than fir, with the alpine association of a plant that can grow at higher elevation than almost any other tree.

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.
