Vivid Clan Turquoise
Vivid Clan Turquoise (#0CD8CD) is a true cyan with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (177°, 89%, 45%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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
From the Latin vividus, full of life — used as a color modifier since the late sixteenth century for hues that read as luminous and saturated. Vivid red, vivid blue: the implication is that the color appears almost lit from within, with the optical brightness of a high-chroma surface in good light. Sits at the bright-bucket center alongside bright and electric.
Scottish-Gaelic clann, children / family. As a color modifier, clan implies a Highland-Scottish-kinship quality, the visual register of Scottish-Highland-Clan Highland-and-Lowland hand-woven tartan-and-kilt-and-broadsword clan-and-kinship surfaces under Highland-Scottish-clan tartan-and-kilt-and-pipe-band Highland-pasture light. Sits at the modifier-and-cultural end of the grid, parallel to tribe and kin in usage.
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.

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.
