the white disc has rainbo press code too , i do not know about the black disc , i know the silver disc is much more common then the white or black disc , i have never found a black disc one , i have found the white one twice , and the silver one too many times to count , that is why i think the black or white one is 1st press , i know the silver has rainbo code on it but so does the white disc , and the white disc has it in big letters the same way og b.o.m. does and countless others
