Disciplined Sininen
Disciplined Sininen (#0B6885) 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 (194°, 85%, 28%) 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
Latin disciplīna, teaching / training — past-participle of discipline. As a color modifier, disciplined implies a clear-and-controlled-and-careful quality where the hue carries the visual register of careful-edited-and-restrained design-decision. Sits at the crisp-and-orderly end of the grid, parallel to methodical and orderly in usage.
The Finnish word for blue — used for the Suomenlippu (Finnish flag) and the saturated blue of Finnish lake water. Sininen covers the entire blue-cyan spectrum in Finnish color vocabulary. The color refers to a Finnish lake at midsummer: a saturated, slightly cool deep blue with the optical depth of clear glacial-lake water.

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.
