Sharp Bluestem

#66ecae
Notes

Sharp Bluestem (#66ECAE) is a true teal 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 (152°, 78%, 66%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sharp
adjective

Old English scearp, cutting, pointed — applied metaphorically to color since the seventeenth century for hues that read as definite and edge-defined. Sharp red, sharp green: the implication is saturation combined with high-contrast crispness. Sits in the bright-bucket center alongside crisp and clear, with a slightly more incisive edge.

Bluestem
noun

The genera Andropogon and Schizachyrium — North American native prairie grasses whose stems shift from green to blue-purple in autumn. The color refers to S. scoparium (little bluestem) in midsummer: a soft, slightly cool blue-green-gray with the matte finish of upright prairie grass.
