Surveyed Tyrian
Surveyed Tyrian (#ECB3E7) is a soft violet with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (305°, 60%, 81%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old French surveer, to look upon — past-participle of survey. As a color modifier, surveyed implies a clear-and-measured-and-coordinated quality, the crisp color of Mason-Dixon-Line-and-Royal-Navy-Hydrographic scientific-and-cadastral land-and-sea surveying tradition. Sits at the crisp-and-mapped end of the grid, parallel to mapped and plotted in usage.
Historical Phoenician Tyrian purple (purpura) — derived from the Bolinus brandaris and Hexaplex trunculus sea-snail hypobranchial-gland secretion, processed at industrial scale on the Lebanese coast from 1500 BCE to 1453 CE. Tyrian color refers to a freshly Tyrian-purple-dyed Roman toga picta: a saturated, slightly cool deep violet with the matte finish of multi-bath Murex shellfish-dye on woolen toga cloth.

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.
