Ever since Vanta Black I've been super curious about this stuff. I bought the new Black 4.0 and was blown away. Compared it my blackest matte black paint (left), black paper, black 4.0 (middle) and sharpie (right). The black paint looks grey in comparison! If you need something very black this is the real deal.
However, it is NOT at ALL like they show in pictures where things just turn into a black hole in space. To get those photos they need very specific lighting. In normal light it doesn't look like anying special. Only in the right low to medium light does it give the effect.
Vanta Black isn’t a paint, it’s an achievement of materials science. It very much does look like a black hole in space in the real world. These “blackest black” paints are just clout chasing by some guy attempting to profit from the situation where a materials science company doesn’t want to work with thousands of artists, because their real customers are like defence and telecom companies, and they are nothing like the real Vanta Black.
Isn't Black 4.0 supposed to be about as black (absorbs 99.96% of visible light) as Vantablack, even though it's just "a paint"? (I have no idea what it's made of)
So in other words, Black 4.0 'just a paint' is imperceptible from Vantablack using human vision, and the Anish Kapoor thing was just a publicity stunt?
Looking at it the other way, Black 4.0 reflects 0.05% of the light, and Vantablack 0.035%. So Black 4.0 reflects about 40% more light. The difference is not that small.
On the other hand, Vantablack is highly toxic (similar to asbestos), while Black 4.0 should be quite a lot safer.
Right but 40% of something very small is also very small. If you are experiencing the two blacks in a normal ambient environment around lighting and other non highly light absorbent surfaces, they will look extremely similar.
No, the logarithmic effect bottoms out towards the low part of the scale. If you're somewhere very dark, your eye adjusts so that you get back to the middle of the range. But if you're somewhere light and just looking at black paint, it doesn't.
Having seen his exhibit in Venice. I will say, in the right contexts it really does look like a black hole. This doesn’t require limited lighting, just regular room lighting. 3d objects painted with it will disappear into themselves as if it was 2d.
It's easy to make black material that is very black measured perpendicular.
Low total hemispherical reflectance is what makes Vanta Black different.
You don't see it in other paints like Black 4.0.
Possible experiment: If you could spray very thin layer of Black 4.0 into a black velvet or one of those nanofiber cloths (so thin that it's not covering the texture) you might improve total hemispherical reflectance.
There is a science/maker that showed off the true blackest black by shining a bright light on each of them. One was the clear winner - then he revealed he faked it. It was really just a hole into a box. Quite the illusion. I can't find it right now to link it.
A nanotubes coating (like VB) might have better range as it operates differently: from my understanding the coating “traps” light as in a maze, it does not “just” try to limit reflection.

"It all started when Kapoor landed the exclusive rights to use the pigment Vantablack, billed as the world’s darkest pigment and said to absorb 99.96 percent of light."
Hahaha IIUC Anish Kapoor, a British spectacle-based celebrity pop artist, did some silly bullshit where he arranged an exclusive contract for purchase of one of one of these blackest-ever paints (might have been Vanta?) so that the only way you could experience it was by visiting his exhibitions.
I guess the person making this new paint thought this was, well, bullshit, so this is a response to that :)
