Lucid Seagrass

#cdf7dd
Notes

Lucid Seagrass (#CDF7DD) 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 (143°, 72%, 89%) 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

Lucid
adjective

Latin lūcidus, clear / bright — derived from lūx (light). As a color modifier, lucid implies a clear-and-readable quality where the hue is unambiguous and free of optical clutter. Sits at the crisp-and-clear end of the grid, parallel to pellucid and plain in usage.

Seagrass
noun

Marine flowering plants — distinct from algae — that form underwater meadows in shallow coastal waters worldwide. Genera include Zostera, Posidonia, Thalassia. The color refers to a tropical seagrass meadow at low tide: a soft, slightly cool deep blue-green with the satin finish of submerged grass-leaves.
