Right, did a bit of research today at work, I have some very old ICI colour reference books, and should be taken as "Gospel"
There are 2 version of SCHWARZBLAU (Blue Black) and thats not 2 different shades, but 2 entirely different colours, separated by many years,
and advancement it paint technology, and the resurrection of an old colour.
1, L52M Schwarzblue 1970 to 1975, was a basic metallic, 3 base tinters, and a medium aluminium fleck to make it a metallic.
2, LP5T Schwarzblue M, 1990 to 1992, was a full on pearl colour, 3 base tinters, and 3 pearl tinters (Red, Blue, Green)
So it looks like VW resurrected L52M from the 1970s for its flagship Mk2 GTI's, up until the face lift BB model, when VW introduced LP5T with their increasing range of Pearl colours... Bright Blue metallic, and Pearl Grey, replacing Atlas Grey of which there still seems to be a great deal of confusion over, but thats another story, I also now need to check whether BBM is actually a Pearl
The lack of certain colours from the GTI colour guides earlier in this thread, point to Schwarzblau being a Special order only, or, my educated guess, is that its likely that it may have been a colour designated for demonstrator cars supplied to the Dealers, but that is a guess...
