Tissue Selkie
Tissue Selkie (#D4FEF5) is a soft teal with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (167°, 95%, 91%) places it in the highly saturated band at a light 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
Old French tissu, woven-cloth — adjectival usage of tissue. As a color modifier, tissue implies a pale-and-thin-and-translucent quality, the pale color of Edwardian-period fine-tissue-paper gift-wrapping-and-archival-protection thin-and-translucent paper-finish. Sits at the pale-and-thin end of the grid, parallel to onionskin and glassine in usage.
The seal-people of Celtic folklore — particularly Scottish, Irish, and Faroese mythology — beings who shed sealskin to take human form. Selkie color refers to the deep blue-green of Atlantic waters where the seal-folk are said to live: a deep, slightly cool deep blue-green with the optical complexity of cold Atlantic open water.

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.
This color sits well within the sRGB cube. P3 and sRGB share the gray axis and most desaturated tones, so a P3 display renders this identically to an sRGB display.
