Regal Stola

#8720a9
Notes

Regal Stola (#8720A9) 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 (285°, 68%, 39%) 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

Regal
adjective

Latin rēgālis, kingly — derived from rēx (king). As a color modifier, regal implies a saturated-and-royal-formality quality, the deep-rich color of British-Coronation-period royal vestment-and-mantle and Imperial-State-Crown regalia. Sits at the bold-and-imperial end of the grid, parallel to sovereign and royal in usage.

Stola
noun

The Roman matron's long ceremonial robe — particularly the stola worn by Roman empresses and vestal virgins, often dyed in graduated Tyrian purple layers as a marker of social rank. Stola color refers to an imperial Roman Livia-period stola: a saturated, slightly cool deep violet with the matte finish of multi-bath Tyrian shellfish-dye on Roman wool. Distinct from the unmarried-woman tunica and the slave colobium.

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.
