Vivid Seafoam
Vivid Seafoam (#02E6CB) is a true teal 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 (173°, 98%, 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.
The pale, slightly translucent green-blue of foam on a breaking wave — light scattered through micron-scale air bubbles in salt water, with a touch of the sea's color showing through. Seafoam green refers specifically to that desaturated tint: a soft, very pale green-blue with the optical lightness of small bubbles in motion. Lighter than mint, cooler than celadon.

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.
