Why Stuart Semple Invented BLACK 4.0: The Full Story

The origin of the world's blackest black paint

In 2014, British sculptor Anish Kapoor struck a deal with Surrey NanoSystems to be the sole artistic user of Vantablack, at the time the darkest substance known to science. Artists worldwide were outraged: a fundamental colour had been privatised for one person's use.

Stuart Semple, a British artist known for his work with colour and accessibility in art, responded in the most direct way possible: he made his own super-black paint and released it to everyone.

The only condition? You must confirm you are not Anish Kapoor.

From protest to pioneering art material

What began as a statement became something more significant. Semple and his team at Culture Hustle realised they could push the technology, not just match Vantablack in accessibility, but create a genuinely extraordinary artist-grade super-black that exceeded what was available to the market.

The first version, Black 3.0, became a global phenomenon, used by thousands of artists, referenced in art criticism, and covered by media worldwide. But the lab kept working.

BLACK 4.0: The perfected super-black

After several years of reformulation, BLACK 4.0 arrived in 2023. It achieves at least 99.8% light absorption, using a new acrylic binder technology, advanced mattifiers, and a proprietary black pigment system.

What changed from 3.0 to 4.0: - Traps more light (higher absorption %) - Lays flatter on surface - Covers better in fewer coats - More robust and durable once dried - Works better on more surface types

What BLACK 4.0 means for artists

The visual effect is genuinely arresting. Objects painted with BLACK 4.0 lose their three-dimensional appearance, the eye cannot read the contours because there is no reflected light to create shadow gradients. A sphere painted with BLACK 4.0 looks like a flat disc. A hand looks like a black silhouette.

This optical quality has been used by artists worldwide for: - Paintings exploring perception and void - Sculptures that appear to defy three-dimensionality
- Installations exploring light and darkness - Set design and immersive art experiences - Conceptual works about absence, negation, and anti-visibility

Stuart Semple on colour and access

The BLACK 4.0 story is part of a wider philosophy. Culture Hustle exists because Semple believes extraordinary colour should be democratised, available to every artist regardless of resources. Every product in the range is priced to be accessible, non-toxic, and made to artist standards.

"I wanted to make things that actually help artists make better work. Things that didn't exist, or that were too expensive, or that were locked away. Colour should be for everyone." - Stuart Semple

The Vantablack rivalry: where it stands

The rivalry between Semple and Kapoor continues to play out culturally. BLACK 4.0 now exceeds what was publicly available in terms of accessibility and artist-friendliness, even if Vantablack's nanotube coating remains technically distinct. The real victory was never about winning a measurement, it was about proving that extraordinary materials can be democratised.
