Rusticated Vortex
Rusticated Vortex (#061511) is a deep teal with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (164°, 56%, 5%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin rūsticātus, country-roughened — past-participle of rusticate, sharing root with rural. As a color modifier, rusticated implies a neutral-and-rough-and-rural quality, the neutral color of Italian-Renaissance-and-Florentine-palazzo rusticated-stone-base architectural-and-rough-textured ground-floor-stonework. Sits at the neutral-and-traditional end of the grid, parallel to rustic and weathered in usage.
Latin vortex, whirl — the deep-cool-gray rotating-fluid structure of tornado, waterspout, and whirlpool phenomena. Vortex color refers to a Niagara-Falls whirlpool downstream of the Horseshoe Falls: a dark cool-gray with the optical complexity of high-velocity downstream-current-mixed Niagara-River water against the Niagara Gorge shale cliff-face.

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.
