Why do black objects reflect light?
I thought they absorb light, not reflect it?
Am I missing something?

Cause they aren't true black. Most blacks we see are really just super dark shades of green or purple.
So you're saying it's like that thing with none of our spherical objects being truly round?
That is exactly it.
>Most blacks we see are really just super dark shades of green or purple.
That's racist
Fucking lol.
I got bullied for this once.
I take it you've never seen anything covered in Vantablack 2.0 in person. It is like a fucking hole in reality.
Any non-metallic material has a roughly 5% chance of reflecting any photon that hits it. The other 95% of light will enter the surface, bounce around inside, and then do one of 2 things:
1. become absorbed. The object will look black with a white highlight
2. exit the surface again. The object will be [color of light that exited] with a white highlight.
You need to very carefully craft a surface structure that traps light inside, in order to not reflect that 5% of light (think: soundproof foam in audio recording rooms, but for light instead of sound. Pic related).
That's some Aperture science shit right there
...
Most are a shade of blue
They are actually white, the reflection is all colors.
Wrong, lmao. The color is as we perceive it
What color are the parts with reflections on them?
Protip: Not fucking black.
You deserved it.
black clothes are actually really dark red
you can think about it as reflection and resonance. reflection is the light simply reflected from the surface and reflected waves has the same frequency as before, but resonance is when light waves actually penetrates surface and the surface kinda "resonate" at one specific frequency (color)
It's actually not a matter of being a non-true black. It has to do refraction on the surface and shit and the angle of the light.
Fucking kek lmao
I want to see vantablack irl
grindr
As a private individual you can't just buy it.

It's subject to export controls. I guess someone thinks it could be "weaponized", though I'm not sure how.
You may have to be satisfied with photos
I remember some lab was making a true black panel to calibrate some shit with carbon nanotube, they took pics of the thing and i can asure you it didn't reflect anything it seemed a hole, it would be nice of me if i took the effort of looking for the pic but i am lazy

That's what happens when you make something cool in the UK, you end up needing a license for it
