Elemental Calcite
Elemental Calcite (#B1AFB4) is a balanced neutral with a mono character. It's a grayscale value, at home in typography, dividers, and the structural layer beneath stronger colors. Its HSL profile (264°, 3%, 70%) places it in the muted band at a mid lightness. It works well as secondary text, borders, and placeholder states. A reliable middle gray that reads cleanly in either light or dark contexts. Pair it with almost any saturated accent. It's built to sit underneath or behind stronger colors without fighting them.
Etymology
Latin elementum, element — adjectival suffix -al. As a color modifier, elemental implies a neutral-and-foundational-and-natural-element quality where the hue carries the visual register of earth-and-stone-and-water-and-air foundational-and-elemental natural-mineral-and-pigment surface. Sits at the neutral-and-foundational end of the grid, parallel to foundational and primal in usage.
CaCO₃ calcium-carbonate mineral — the principal mineral of limestone-and-marble, mined principally in Italian-Carrara and English-Cotswold-quarries. Calcite color refers to a freshly cleaved Iceland-spar calcite-crystal rhomb face: a pale cool gray with the glassy finish of trigonal-system calcium-carbonate with the characteristic calcite birefringence (double-refraction).
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.

This color has effectively no chroma (OKLCH C = 0.007) — 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
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.
