Invigorating Crocus

#a181ec
Notes

Invigorating Crocus (#A181EC) is a soft 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 (258°, 74%, 72%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it.

Etymology

Invigorating
adjective

Latin vigor, vigor — present-participle of invigorate, sharing root with vigil (watchfulness). As a color modifier, invigorating implies a saturated-and-life-giving-and-energizing quality where the hue increases visual-and-physical vitality. Sits at the bright-and-active end of the grid, parallel to stimulating and bracing in usage.

Crocus
noun

The genus Crocus — small autumn or spring corms that flower before their leaves emerge, push through snow in March, and include C. sativus, the source of saffron. The color refers to a fresh blue-violet spring crocus: a saturated, slightly violet-shifted deep blue with the satiny finish of a six-petaled cup catching morning light. Cooler than amethyst, warmer than iris, with the seasonal weight of a flower that arrives weeks before everything else.
