Did you notice that some colors on the ABS color ring have a different slightly transparent material. They look a bit like jelly. Is it just the plastic chips or will the key caps have the same material? You can recognize these colors on the raised Signature Plastic logo, the bad colors don't have a black shadow there and feel a bit more "slimey". Some of these colors e.g. are BFK, BO, OBC, VCJ, VV, YCA (extreme).
BTW. did somebody use the gray GAY for his keys? :tongue1: Strangely raised on the front it says "6AY".
