Grounded Petunia

#ca3bb4
Notes

Grounded Petunia (#CA3BB4) is a true 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 (309°, 57%, 51%) 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

Grounded
adjective

Old English grund, bottom / foundation — past-participle of ground. As a color modifier, grounded implies a saturated-and-foundational quality where the hue anchors the surrounding palette through its weighty presence. Sits at the bold-and-balanced end of the grid, parallel to centered and anchored.

Petunia
noun

Petunia × atkinsiana, the modern garden hybrid bred from South American Petunia species in the nineteenth century — now the most-planted annual bedding flower in North America. The color refers to a deep purple petunia in summer container bloom: a saturated, slightly red-shifted deep purple with the satiny finish of trumpet-shaped flowers. Cooler than orchid, warmer than violet, with the bedding-plant weight of a genus bred for nearly endless color and continuous bloom.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
