Stately Nocturne
Stately Nocturne (#7E5EF8) is a true indigo 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 (252°, 92%, 67%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary yellow. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
An adjectival form of state, condition of dignity. Used as a color modifier since the seventeenth century for the deep saturated jewel tones of formal ceremony — the deep blue of a robes-of-state, the deep red of a state-banquet velvet. Sits in the bold-and-formal corner alongside imperial and royal, with slightly less institutional weight.
French nocturne, night-piece — adopted into music by John Field (Irish, 1812) and Frédéric Chopin (Polish, 1827–46) for piano character pieces evoking nighttime, and into painting by James McNeill Whistler for a series of deep-blue-violet Thames-river twilights. Nocturne color refers to a Whistler Nocturne in Black and Gold foreground tonality: a saturated, slightly cool deep blue-violet with the soft finish of thinned oil over warm gesso.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
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.
