Robust Picotee

#4381fa
Notes

Robust Picotee (#4381FA) is a true azure with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (220°, 95%, 62%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Robust
adjective

From the Latin robustus, of oak — implying strength combined with substance. As a color modifier, robust describes saturation combined with body: a robust burgundy, a robust olive. Sits in the bold-and-warm corner alongside strong and solid, with the slightly textural implication of a color that has substance behind the pigment.

Picotee
noun

A botanical term for a flower with edges colored differently from the body — Picotee roses, Picotee sweet peas, Picotee dahlias all have a crisp white or contrasting band along the petal margin. The color Picotee blue refers to a saturated body-color blue used as the dominant petal field: a saturated, slightly violet-shifted deep blue with the matte finish of high-density flower petal. Cooler than royal, warmer than indigo.
