It’s so black, it’s like how much more black can it be?
.05%
I want one.
Rappers everywhere are taking notes
For comparison Vantablack absorbs 99.965%.
None. None more black.

Can't wait for them all to be poached to death now.
So, what happens if something is 100% black? Would it literally be like the video DaBeaver posted above?
Essentially, yes. You we see the silhouette, with no detail what so ever. No matter how complexe the actual object, it would appear 2 dimensional.
honestly i doubt 0.05% makes much difference to our eyes at least. nothing to back this up, just a hunch
It does make a lot because it means you can detect details, as opposed to none at all.
Blacker than the blackest black times infinity.
It's so impossibly black.
Human eyes don't see light linearly though, so to our eyes it would be more like 3% Human eyes are really good at seeing contrast in very dark colors.
I've heard it used to be the kang king of all birds
If you google image search Vantablack you can get an idea. It looks...unnatural. Like a bad Photoshop.
It best be careful, they might arrest it for loitering.
Important to remember that this is practically impossible in real-life, because of contaminants and dust ruining the purity.
Weird how this article is basically a reposting of a January Wired Article and almost nothing unique to itself.
so fucking metal oh my god uhhhhh [growls into eternity]
Well, 100% absorption would make it a near perfect blackbody radiator, but still not actually "100% black". All the energy absorbed would be re-emitted back out as light in the form of heat radiation. It could still look 100% black to us, but not if you had a thermal camera on hand or it was radiating enough energy to glow in the visible part of the spectrum, like hot metal. It's physically impossible to make a truly 100% black object however. The closest real thing to what you're asking would actually be black holes. Lava is also a good example as it's extremely dark when cool, so its temperature can be estimated from color alone. True black would require that energy was only absorbed by the material but never emitted as light, so you would just get a ticking time bomb.

Just .01% difference is impossible to represent in current 32 bit color. 256 color is too limited to actually shwo a difference, but the naked Human eye would be able to spot it. It'd be espcially notable if placed next to bright greens.
This was the first thing I thought since blacker than very black black is worth a lot of money
Given how good the brain is at perceiving differences I'd say it's pretty likely you would notice, especially side by side.
Finally a bird that reflects my soul
