I ordered some black paint a while back, and after some discussion this was amended to black black.
This ensured that it had no component red, blue, green, yellow or any other colour you can think of
added to it in the formulation stage. It was noticeably blacker than what I've seen before.
I have seen it said that there is no black like
BMW Black, but perhaps you don't want to go down that path !
Gosh, I just had a captcha with motorcycles ...
