Midnight Quartz
Midnight Quartz (#453922) is a deep amber 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 (39°, 34%, 20%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
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.
Silicon dioxide — the most abundant single mineral on Earth's continental crust, occurring as everything from beach sand to gem-grade rock crystal. Quartz as a color refers to a polished pale-gray quartz crystal: a soft, very pale slightly cool gray with the high specular shine of a translucent silicate. Cooler than pearl, warmer than mist.

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.
