The blackest black paint ever

look to the deep sea fish if you want to understand black

of course this is science based, not the stuff of faux fantasy

IF you look hard enough, eventually you will find (see ) Schrodinger’s cat

only the serious will understand this

It's like how much more black could that be? The answer is none. None more black.

Not to oversimplify it, but there is only "1" black colorant made for the entire paint/dye industry, and it's called lamp black.  And all black paints are made from a clear base, and that goes for any type of paint produced.  So, unless the clear base is milky to begin with, or there is some other colorant in the mix...BLACK IS BLACK.  If your base is truly clear, and you're using lamp black only, you can't get any blacker.  Now...not to confuse anyone, but ALL paints start as a clear, then white is added and color bases are created from that.  How do I know this...39 years in the industry it's amazing what you learn.
