Hellish Oxford
Hellish Oxford (#132B84) is a deep 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 (227°, 75%, 30%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English helle, hell — adjectival suffix -ish. As a color modifier, hellish implies the deep-glowing-furnace-darkness of Dante-and-Bosch infernal-imagery, where heat and shadow combine in the painted-and-poetic Christian underworld. Sits at the deep-and-warm end of the grid, parallel to infernal and warmer than plutonian.
The athletic blue of the University of Oxford — adopted alongside Cambridge's lighter blue in the 1820s, when the two universities first began racing crews against each other on the Thames. The color refers to an Oxford-blue rowing jersey: a saturated, slightly muted deep blue with the matte finish of melton wool. Deeper than navy, cooler than royal, with the rivalrous heraldic weight of a color paired with its institutional opposite.

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.
