Pellucid Mizu
Pellucid Mizu (#1D6484) is a deep cyan with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (199°, 64%, 32%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary orange. 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.
The Japanese word for water — used as a color word for the saturated pale blue of fresh spring water and the mizu-iro of traditional kimono linings. Mizu spans the cyan-blue boundary in Japanese color vocabulary. The color refers to fresh spring water in a Kyoto stone basin: a soft, slightly cool pale blue with the optical clarity of cold mineral water.

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.
