Ominous Modré
Ominous Modré (#1939A1) is a true blue 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 (226°, 73%, 36%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary amber. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin ōminōsus, full of foreboding — derived from omen. As a color modifier, ominous implies a deep-and-threatening atmospheric-foreboding quality, the dark cool-gray of Goyaesque storm-laden sky. Sits at the deep-and-threatening end of the grid, parallel to foreboding and menacing in tone.
The Czech word for blue — used for the saturated deep blue of Czech traditional Modrotisk (blue-print) folk-textile resist-dyeing. Modré covers the entire blue spectrum in Czech color vocabulary. The color refers to a freshly Modrotisk-printed cotton: a saturated, slightly cool deep blue with the matte finish of plant-dyed-resist-printed cotton.

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.
