Stern Vienna
Stern Vienna (#202C90) 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 (234°, 64%, 35%) 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
Old English styrne, strict / firm — sharing root with stark. As a color modifier, stern implies a deep-and-uncompromising quality, the dark formal-Calvinist plain-textile color of stripped-down Protestant-and-Quaker tradition. Sits at the deep-and-formal end of the grid, parallel to austere and severe in tone.
Austro-Hungarian imperial capital — and the Wiener Werkstätte color tradition of deep-violet Sezession secessionist textiles in the early 20th century. Vienna color refers to a Hoffmann-designed Wiener Werkstätte embroidered cushion cover (1903–1932): a saturated, slightly cool deep blue-violet with the matte finish of vat-dyed worsted wool. Cooler than the Wittgenstein family's pre-war Vienna interior aubergines.

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.
