Plotted Ruff Teal

#01b4a0
Notes

Plotted Ruff Teal (#01B4A0) is a true teal with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (173°, 99%, 35%) 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

Plotted
adjective

Old English plot, small piece of ground — past-participle of plot. As a color modifier, plotted implies a clear-and-coordinate-mapped quality, the crisp color of Cartesian-and-graph-paper coordinate-plotted scientific-and-engineering data-visualization plot-line. Sits at the crisp-and-mapped end of the grid, parallel to mapped and surveyed in usage.

Ruff
modifier

Old English ruffe, Elizabethan-pleated-collar. As a color modifier, ruff implies a starched-and-Elizabethan-pleated-collar quality, the visual register of Elizabethan-and-Spanish-Habsburg-ruff hand-starched-and-Elizabethan-pleated-collar Elizabethan-and-Spanish-Habsburg-ruff-and-Holbein-portrait ruff-and-starched-and-Elizabethan-pleated-collar surfaces under Elizabethan-and-Spanish-Habsburg-ruff-and-Holbein-portrait Tudor-and-Spanish-Habsburg-court starched-collar-light. Sits at the modifier-and-textile end of the grid, parallel to gown and frock in usage.

Teal
noun

Anas crecca, the small dabbling duck whose male in breeding plumage sports a chestnut head crossed by a glossy green-blue stripe. The color refers to that stripe — the iridescent panel just behind the eye: a saturated, slightly muted blue-green with the optical depth of structural color rather than pigment. Cooler than cypress, warmer than cerulean, with the ornithological specificity of a color named for one feather of one bird.
