Pellucid Empress
Pellucid Empress (#B5A3EE) is a soft indigo with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (254°, 69%, 79%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. 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
Latin pellūcidus, transparent — derived from per-lūcēre (to shine through). As a color modifier, pellucid implies a clear-and-translucent quality where the hue reads with optical clarity and minimal turbidity. Sits at the crisp-and-clear end of the grid, parallel to lucid and translucent in usage.
Latin imperatrix via Old French empereïs — the female sovereign of an empire, particularly the Empress Theodora of Byzantium (sixth century) whose San Vitale mosaic portrait wore the deep-violet Tyrian purple imperial robes. Empress color refers to Theodora's deep-violet imperial robe in the San Vitale mosaic: a saturated, slightly cool deep blue-violet with the matte finish of murex-and-indigo-overdyed Byzantine 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.
