Coruscating Shikon
Coruscating Shikon (#AF79F2) is a soft 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 (267°, 82%, 71%) places it in the highly saturated band at a light 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin coruscāns, flashing — present-participle of coruscāre. As a color modifier, coruscating implies a saturated-and-rapidly-flashing quality, the bright color of lightning-strike atmospheric-electrical-discharge against the night-sky. Sits at the bright-and-flashing end of the grid, parallel to flashing and flickering in usage.
Japanese 紫根, gromwell root (Lithospermum erythrorhizon) — the purple-root dye source for traditional Japanese murasaki and the medicinal-herb base for the eponymous shikon ointment used in burn treatment. Shikon color refers to a freshly harvested Lithospermum erythrorhizon root cross-section: a saturated, slightly cool deep violet with the matte finish of fresh root dye on hand-spun silk.

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.
Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
