Phosphorescent Tibouchina
Phosphorescent Tibouchina (#C86DE6) 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°, 71%, 66%) 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
Greek phōsphóros, light-bringer — adjectival suffix -escent. As a color modifier, phosphorescent implies a saturated-and-cool-glow-after-stimulation quality, the bright cool-green-blue color of Cu-doped-ZnS glow-in-the-dark photoluminescent surfaces. Sits at the bright-and-cool end of the grid, parallel to fluorescent and luminous in usage.
South American princess flower (Tibouchina urvilleana) — a Brazilian cerrado native shrub cultivated worldwide for its silver-veined leaves and deep-violet five-petaled flowers. Tibouchina color refers to a fully bloomed Tibouchina urvilleana corolla: a saturated, slightly cool deep violet with the velvet finish of fresh broad-petaled corolla. The genus name is from the Tupi-Guarani native word for the plant.

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.
