Pellucid Aquamarine
Pellucid Aquamarine (#9FF1B3) is a soft green with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (135°, 75%, 78%) 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 magenta. 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.
An iron-tinged variety of beryl — the gemstone mined from pegmatite veins in Brazil, Madagascar, and the Pakistani Karakoram. Named for the Latin aqua marina, seawater. The color refers to a faceted Santa Maria aquamarine: a clean, slightly green-shifted blue with the gem's high refractive brilliance. Lighter than sapphire, deeper than seafoam, with the gem-trade specificity of a stone graded primarily for color depth.
