Glowering Enji
Glowering Enji (#43131F) is a deep red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (345°, 56%, 17%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Middle English gloweren, to stare angrily — present-participle of glower, sharing root with glower and gloom. As a color modifier, glowering implies a deep-and-warm-and-glowering-resentful quality, the dark warm-orange of furnace-mouth-and-Volcanic-vent embered glow. Sits at the deep-and-warm end of the grid, parallel to smouldered and hellish.
A dark crimson lake pigment in Japanese textile and lacquer tradition — derived from coccus scale insects and used in the deep underrobes of Heian court dress. The color refers to a enji-dyed silk: a deep, slightly cool dark red with the velvet matte finish of multi-bath dyeing. Deeper than akane, cooler than karakurenai. The hue Murasaki Shikibu would have worn beneath an outer robe.

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.
