Grim Moonlight
Grim Moonlight (#2A328F) is a true blue with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (235°, 55%, 36%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary yellow. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English grimm, fierce / fierce-faced — sharing root with German grimm and Old Norse grimmr. As a color modifier, grim implies a deep-and-cool-and-comfortless-formal quality, the dark cool-gray of Norwegian-fjord mid-winter atmospheric-overcast light. Sits at the deep-and-cool end of the grid, parallel to bleak and stern in atmospheric register.
The spectrally cool reflected sunlight of a full moon — about 400,000 times dimmer than the sun and slightly redder than direct sunlight due to lunar regolith reflectance, but perceived by dark-adapted scotopic vision as deep blue-violet. Moonlight color refers to a clear-sky landscape under full moonlight as photographed long-exposure: a saturated, slightly cool deep blue-violet with the optical complexity of Purkinje-shifted scotopic-perception lighting.

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.
