Pragmatic cyan
Pragmatic cyan (#13918C) is a deep cyan 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 (178°, 77%, 32%) places it in the highly saturated band at a dark 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
Greek pragmatikós, of business / practical — adjectival suffix -ic. As a color modifier, pragmatic implies a clear-and-purpose-fit-and-no-nonsense quality where the hue carries the visual register of straightforward-utilitarian-and-functional decision-making. Sits at the crisp-and-functional end of the grid, parallel to practical and functional in usage.
From the Greek kyanos, deep blue, originally referring to the lapis-derived blue of antiquity. In modern usage, cyan is one of the four printing primaries (with magenta, yellow, and black) and an additive primary on screens. The color refers to a pure CMYK cyan tile: a saturated, clean blue-green with the optical brightness of an additive-color primary. Cooler than turquoise, lighter than cerulean, with the technical specificity of a color defined by a printing-press standard.

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.
