Considerate Midnight

#01113b
Notes

Considerate Midnight (#01113B) is a deep azure 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 (223°, 97%, 12%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Considerate
adjective

Latin cōnsīderātus, thoughtful — past-participle of consider. As a color modifier, considerate implies a neutral-and-thoughtful-and-careful quality where the hue carries the visual register of careful-and-thoughtful-and-considerate coordinated color-decision matched to its surroundings. Sits at the neutral-and-friendly end of the grid, parallel to thoughtful and mannerly in usage.

Midnight
noun

The color of the sky at midnight on a clear, moonless night, far from city lights — almost black, but with a slight blue cast where star-scattered light reaches the eye. The color refers to that exact moment: a very deep, slightly violet-shifted near-black blue with the optical depth of a sky stripped of every direct light source. Deeper than navy, warmer than ink, with the temporal weight of a name that is a precise hour as well as a color.
