Loud Caper Turquoise

#30dccd
Notes

Loud Caper Turquoise (#30DCCD) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (175°, 71%, 53%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Loud
adjective

Old English hlūd, making noise — borrowed metaphorically as a color word since the nineteenth century. Loud red, loud yellow: a color so saturated it announces itself without needing surrounding context. Sits in the bright-bucket extreme alongside electric and striking. Carries a slightly pejorative implication of excess.

Caper
modifier

Greek κάππαρις, Mediterranean-pickled-bud. As a color modifier, caper implies a Mediterranean-pickled-bud-and-briny-tang quality, the visual register of Pantelleria-and-Sicilian-caper hand-Mediterranean-pickled-bud-and-briny-tang Pantelleria-and-Sicilian-caper-and-Aeolian-Islands caper-and-Mediterranean-pickled-bud surfaces under Pantelleria-and-Sicilian-caper-and-Aeolian-Islands Pantelleria-and-Aeolian-and-Sicilian Mediterranean-brine-light. Sits at the modifier-and-flavor end of the grid, parallel to anise and tang in usage.

Turquoise
noun

The hydrated copper-aluminum phosphate mined in Persia and the American Southwest for thousands of years — the firuze of Iran, the chalchihuitl of Mesoamerica, the heart of Pueblo and Navajo silverwork. The color refers to a fine Sleeping Beauty turquoise from Arizona: a saturated, slightly green-shifted blue with the slight matrix of host-rock veining. Brighter than persian, lighter than cerulean.

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.
