Defined Tatra
Defined Tatra (#D0ADE9) is a soft indigo with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (275°, 58%, 80%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin dēfīnīre, to set bounds — past-participle of define. As a color modifier, defined implies a clear-and-edge-distinct-and-precise quality where the hue carries the visual register of sharp-bounded-and-clearly-delimited surface. Sits at the crisp-and-clear end of the grid, parallel to crisp and sharp in usage.
Carpathian high-mountain range straddling Poland and Slovakia — its alpine tatran peaks above 2,000m support some of Europe's last Soldanella alpina and Gentiana clusii deep-violet alpine flora. Tatra color refers to a Soldanella alpina corolla on a High Tatras alpine ledge: a saturated, slightly cool deep violet with the velvet finish of fresh alpine snowbell petal under high-altitude light.

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.
