Dense Aster

#7b207b
Notes

Dense Aster (#7B207B) is a deep violet 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 (300°, 59%, 30%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Dense
adjective

Latin dēnsus, thick / crowded — sharing root with English condense. As a color modifier, dense implies a saturated-and-tightly-packed quality where the hue carries maximum pigmentation per visual unit-of-area. Sits at the bold-and-saturated end of the grid, parallel to thick and concentrated in usage.

Aster
noun

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.
