Core Silver

#bcb2b5
Notes

Core Silver (#BCB2B5) is a pale 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 (342°, 7%, 72%) places it in the muted band at a light lightness. It works as a soft page background, card surface, or low-key divider. Avoid it for body text against white. Pair it with almost any saturated accent. It's built to sit underneath or behind stronger colors without fighting them.

Etymology

Core
adjective

Old French cor, heart / center — adjectival usage of core. As a color modifier, core implies a neutral-and-central-and-essential quality where the hue carries the visual register of Bauhaus-and-Mondrian-De-Stijl central-and-essential-design foundational-element-and-base-color. Sits at the neutral-and-foundational end of the grid, parallel to central and essential in usage.

Silver
noun

Element Ag, atomic number 47 — the most reflective metal in the visible spectrum, used since antiquity for coinage, mirrors, and tableware. The color refers to freshly polished sterling silver: a clean, slightly cool bright silver with the high specular shine of a polished noble metal. Cooler than sterling, warmer than platinum.

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 = 0.012) — 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.

WCAG contrast

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

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.

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.
