About Vantablack

Vantablack is functionally #000000 taken to a physical extreme — a nanotube coating absorbing 99.965% of light, the “world’s blackest black,” whose EXCLUSIVE licensing to one artist ignited the art world’s most public color feud.

History

Surrey NanoSystems’ Vantablack (2014) absorbs almost all visible light, making 3D objects look like flat voids. Anish Kapoor’s exclusive art-use license enraged artists — Stuart Semple retaliated with the “world’s pinkest pink” (banned from Kapoor), a color war for the ages.

Psychology

The absence of nearly all light reads as void, mystery and the sublime — an unsettling perceptual black hole. It is less a color than a subtraction of vision, and owning it exclusively felt, to many, like owning darkness itself.

In design

On screen, just #000000 (21:1 with white) — no display can reproduce the real material. The exclusivity-feud lesson: Vantablack shows color as PROPERTY taken to absurdity — one artist licensing “the blackest black” sparked a genuine, ongoing color war.

In culture

BMW’s Vantablack car, Semple’s “pinkest pink” revenge (“not available to Anish Kapoor”), the blackest-black debates: the color that started a war.

Large text — 24px regular or 18.66px bold and above — only needs 3:1, so #000000 is enough for headings on white. Non-text elements such as icons, chart strokes and focus rings also sit at 3:1 under WCAG 2.2 (1.4.11).

Colour vision deficiency

deuteranopia · #000000

tritanopia · #000000

Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.

Color scale — 50 to 950

A Tailwind-shaped ramp built around this exact hex. #000000 is pinned to step 950; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

premiumseriousfocusedtimeless

Near-black is the luxury and editorial default, and the base layer of every dark theme.

With almost no chroma left, the family association is barely present; treat it as a neutral that happens to lean this way. The low lightness adds weight and formality.

Worth knowing

Pure black on a bright screen causes halation for many readers. A tinted near-black is kinder.
