Shaded Halo
Shaded Halo (#1C0C34) is a deep indigo 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 (264°, 63%, 13%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English sceadwian, to cover with shadow — past-participle of shade. As a color modifier, shaded implies a hue darkened by overhead-foliage-or-architectural-element occlusion in pre-modern garden-and-courtyard tradition. Sits at the deep-and-obscured end of the grid, parallel to shadowy but more architectural in connotation.
Greek hálōs, threshing floor — adopted into Christian iconography as the circular disc behind the head of saintly figures, traditionally rendered in ultramarine lapis-and-gold-leaf in Greek-school and Russian-school icon panels. Halo color refers to a 14th-century Russian-school Theotokos icon's halo field: a saturated, slightly cool deep blue-violet with the matte finish of egg-tempera-bound ultramarine over gesso ground.

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.
