Appropriately Hades
Appropriately Hades (#1E000F) is a deep magenta 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 (330°, 100%, 6%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin appropriātus, made-one's-own — adverbial-and-adjectival suffix -ly. As a color modifier, appropriately implies a neutral-and-fitting-and-context-aware quality where the hue carries the visual register of context-fitting-and-conventional color-decision matched to its setting. Sits at the neutral-and-traditional end of the grid, parallel to properly and suitably in usage.
Greek Ἅιδης, the unseen — the brother of Zeus and Poseidon who rules the realm of the dead in classical Greek cosmology. Hades color refers to a deep-shadow underworld in Attic 5th-century BCE black-figure pottery: a saturated, slightly cool deep black with the matte finish of carbon-and-iron-tannin pigment on red-figure-style fired Attic ceramic. Brother of Zeus and Poseidon in Hesiod's cosmology.

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.
This color sits well within the sRGB cube. P3 and sRGB share the gray axis and most desaturated tones, so a P3 display renders this identically to an sRGB display.
