Foreboding Heather
Foreboding Heather (#2E0451) 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 (273°, 91%, 17%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English fore-bēodan, to announce in advance — present-participle of forebode. As a color modifier, foreboding implies a deep-and-threatening atmospheric-anticipation quality, the dark cool-gray of advancing-cyclone storm-front cumulonimbus-base. Sits at the deep-and-threatening end of the grid, parallel to ominous and menacing in atmospheric tone.
Calluna vulgaris, the dominant ground cover of Scottish, Irish, and northern English moorland — the small woody shrub whose pink-purple flower spikes color hill country in late summer. The color refers to mature heather in August bloom: a soft, slightly muted pale purple-pink with the matte finish of small clustered flowers covering an entire moor at scale. Lighter than mauve, warmer than lavender, with the moorland weight of a plant whose name names a landscape.

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.
