Im afraid I have the least helpful answer of them all - it uses blues, blacks, browns, reds, clears.... Depending on which model you find, of course.
If you check the Wiki, there's a big guide on how to decipher Cherry's mind boggling model number scheme (If only the designers of the Enigma machine had some of Cherry's engineers on hand...)
Also, there's going to be a UK based suplier of Filco boards, which are more expensive than Cherry G80s, but supposedly much nicer. I've never used the G80 so I can't say whether that is true for definite.
