Spirited Empyrean
Spirited Empyrean (#0EC9FE) is a true cyan with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (193°, 99%, 53%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
An adjectival form of spirit — used as a color modifier since the seventeenth century for hues that read as animate and characterful. Spirited orange, spirited green: the implication is saturation combined with personality, a color that feels like it has agency. Sits at the bright-bucket center alongside lively and vibrant.
The highest sphere of the medieval European cosmos — beyond the celestial spheres, the abode of light. Empyrean in literary color vocabulary refers to the saturated blue of the highest cloudless sky: a saturated, slightly cool deep blue with the optical brightness of light scattered through a clean atmosphere.

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.
