Earnest Thistle

#a33ad0
Notes

Earnest Thistle (#A33AD0) 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 (282°, 61%, 52%) 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

Earnest
adjective

Old English eornost, seriousness, zeal. Used as a color modifier since the nineteenth century for hues that read as committed but unshowy — the working blues of denim, the deep greens of Quaker meetinghouses. Sits in the bold-and-quiet corner of the grid, slightly less luminous than resolute and slightly less institutional than imperial.

Thistle
noun

The thistles — Onopordum, Cirsium, Carduus — spiny composite-family perennials whose tufted purple flower heads adorn the Scottish national emblem and uncountable European pasture margins. The color refers to a fresh thistle flower at peak bloom: a soft, slightly red-shifted pale purple with the matte finish of tufted florets. Lighter than heather, warmer than lavender, with the heraldic weight of a flower that defends itself with thorns.

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.
