Oops, I forgot that Black Diamond was part of the Metajuls line. I'm used to the Metajuls being in brighter silver and gold flakes.
Anyway, tangerine over the metajuls should look sharp. I do remember though, that when you spray the Black Diamond, you will get some 'black' flakes here and there. Not for sure why. Possibly that black tint that they put in there. But it's weird to see brighter candy tangerine sparkles, then you see some dark tangerine sparkles. Almost looks like candy over dirt.
