Known for creating the world’s “pinkest pink” pigment, and later creating his own ultra-black pigments, British artist Stuart Semple’s next mission was to come up with a color that is made of each and every color in existence.

LOVETONE, the world’s most “colorful color,” is a new NFT artwork by the artist which is composed of 16 million pixels representing every digital color in existence. No two pixels in the digital piece are the same. When zoomed out, the individual colors are made invisible to the naked eye, merging together into what looks like a grey square. But upon zooming in, LOVETONE‘s vibrant array of colorful tiles become visible.

“Having produced digital work for decades, I’ve wondered what it would be like to see all the available colors in the RGB color space at the same time, yet it would take many lifetimes to mix 16 million colors in my studio, so without digital art it would be totally impossible to do,” Semple said. “I love the fact that it’s ended up being a color that you can’t see and, as an NFT, just one person will own it, yet in keeping with my work, everyone in the world will be able to see it for free and share it online.”

LOVETONE is available as a 1-of-1 NFT via auction on digital trading platform OpenSea. Bids close on April 25 at 12 p.m. PDT. The color is also available for viewing on BZR, an NFT gallery curated by the team behind 60 Second Docs.
