Any pigment can be black depending on the lighting, but only black can be black in full light.
They are only 99.995% of the way to that using the carbon fibre pigment I described.
Not a mixture of every colour.
No... Just because there isn't enough light to illuminate the object doesn't mean its pigmentation is black. Would you say that an object that is red becomes black if you close your eyes or turn off the lights?
The reason an object is black in full lighting is because it's absorbing all the wavelengths of colored light you can see due to its pigment containing all of those colors. That's why we have black objects that we can see and call "black." Because they're black.
Also, just because I am curious: What do you think a black light is/does?
If I gave you a black and a red ball in the dark you couldn’t tell me which is which.
If you gave me a ball painted with a conventional ’black’ paint and one that was painted with the pigment I described previously in full light I could.
With my naked eyes? No. Because I can't see. But if you put them in a room I couldn't see and gave me the tools to analyze their molecular structure in a room I can see in, I could. (Or well, someone who knows how to use the equipment and read the measurements could anyway lol)
I wouldn’t need any special tools or tool-deciphering experts.
