Surveyed Hyacinthine
Surveyed Hyacinthine (#782F6D) is a deep violet with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (309°, 44%, 33%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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.
Purple dye of late-classical antiquity, mentioned in Pliny the Elder's Natural History (77 CE) as a substitute for the more expensive Tyrian purple, derived from a combination of woad and madder. Hyacinthine color refers to a hyacinthine-dyed Roman toga praetexta border: a saturated, slightly cool deep violet with the matte finish of multi-bath woad-and-madder overdye on woolen toga cloth. Slightly cooler than Tyrian.

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.
