Commanding Aster
Commanding Aster (#752597) is a true violet with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (282°, 61%, 37%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin commendāre, to entrust / order — present-participle of command. As a color modifier, commanding implies a saturated-and-authoritative quality where the hue claims visual leadership of its surrounding palette. Sits at the bold-and-authoritative end of the grid, parallel to authoritative and imperial in usage.
The genus Aster — Greek for star — composite-family perennials whose blue-violet daisy-like flowers fill gardens in September and October when most other bloomers have finished. The color refers to a fresh New England aster (Symphyotrichum novae-angliae): a saturated, slightly violet-shifted blue with the matte finish of multi-rayed composite flowers. Cooler than veronica, warmer than larkspur, with the late-season weight of a flower that closes the perennial year.
