Color Harmony: Custom Scheme
The Onyx Black palette is built using a custom relationship between its hues. This ensures that even with high-contrast accents, the overall scheme feels balanced and intentional.
Hue Wheel
A custom palette is often preferred by professional designers because it balances visual interest with cohesion.
History & Design Context
Black onyx has been carved into cameos and jewelry since antiquity, and the stone reached peak popularity in art deco design. Its deep black with white banding is the classic formal combination.
Best Design Use Cases
Use the near-black for backgrounds in premium contexts, the charcoal for surfaces, and the warm taupe for accents. The bone tone carries body text and contrast.
Industries This Palette Suits
Luxury fashion, jewelry, premium tech, automotive, architecture, high-end hospitality.
Colors That Pair Well With Onyx Black
Need a fifth color? These three companions are computed from the palette's own hue positions on the color wheel, so they extend the scheme without breaking its harmony.
teal
directly opposite #2A2A2A on the wheel — the strongest accent for CTAs and highlights when you need maximum energy
orange
30° beside #2A2A2A — a calm secondary that extends the palette without adding tension
tinted neutral
a paper-white carrying the palette's own hue — perfect for surfaces and dividers
Using Onyx Black Without Breaking Accessibility
- Avoid #2A2A2A for small UI elements on #0A0A0A — at 1.4:1 it misses the 3:1 WCAG threshold; darken it with a shade from the ramp below.
- Set body text in #E8E0D0 — 15.1:1 against #0A0A0A passes WCAG AA (AAA) for long-form reading.
- Let #6A5A4A carry sidebars, cards and footers — at a mid lightness it separates zones without stealing focus from #2A2A2A.
