Pasty Periwinkle

#a39bbc
Notes

Pasty Periwinkle (#A39BBC) is a true indigo 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 (255°, 20%, 67%) places it in the muted 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Pasty
adjective

Old French paste, paste — adjectival suffix -y. As a color modifier, pasty implies a pale-and-doughy-and-flat-surfaced quality where the hue carries the visual register of pale-and-flat-textured dough-and-paste color-finish. Sits at the pale-and-flat end of the grid, parallel to wan and pallid in usage.

Periwinkle
noun

Vinca minor, the trailing groundcover of European woodland whose pale blue-violet flowers gave English the color name in the eighteenth century. Distinct from Catharanthus roseus (Madagascar periwinkle, the source of vincristine for chemotherapy). The color refers to the corolla of a fresh Vinca flower: a soft, slightly violet-shifted pale blue with the matte finish of five-petaled bloom. Lighter than bluebell, cooler than lavender.
