Domestic Diabase

#1f1a16
Notes

Domestic Diabase (#1F1A16) is a deep orange 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 (27°, 17%, 10%) places it in the muted 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

Domestic
adjective

Latin domesticus, of-the-house — derived from domus (house). As a color modifier, domestic implies a neutral-and-household-and-everyday quality, the neutral color of Vermeer-and-Dutch-Genre-painting household-and-everyday interior-and-textile-and-table-still-life finish, often featuring whitewashed walls and earthen-tiled floors. Sits at the neutral-and-traditional end of the grid, parallel to homey and cottage in usage.

Diabase
noun

French diabase, traverse-mineral — the deep-cool-gray fine-grained intrusive-igneous rock of dyke-and-sill emplacement, particularly the Triassic-and-Jurassic Newark-Basin diabase of the New York-and-New Jersey Palisades. Diabase color refers to a New-Jersey-Palisades Newark-Basin diabase cliff-face in midday sun: a dark cool-gray with the matte finish of plagioclase-and-pyroxene intrusive-igneous fine-grained rock.

Closest matches

The nearest named color in three reference sources, ranked by perceptual distance (ΔE76 in CIELAB). ΔE < 1 is imperceptible to most viewers; ΔE > 10 is clearly different. When two sources point to the same hex they’re merged into one tile; click any to open that color’s page.

Harmonies

This color has effectively no chroma (OKLCH C = 0.011) — it’s on the grayscale axis. Hue rotations don’t change a grayscale color, so complementary, analogous, triadic, and split-complementary all reduce to the same value. They aren’t shown because four identical tiles would be misleading.

Accessibility

Color-vision simulation

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.

Display P3 representation

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.
