That's a real bummer. My red is perfect. I was miffed because I had to get a red/white/blue bundle to get the special color, which in my case was transparent. Wish I had gone with black, as well.
The only complaint I have about these cases is there is a post/pole/shaft which sticks up from the badge indentation. I looked at the original case and it is not present but might have been an injection hole or something (I know nothing about it, really.) But I just clipped it with some snippers and put a badge there. Done.
My guess is after 23 years being out-of-production there is no real way to match the original color as I bet even in perfect storage the colors will have changed.
In any case I wasn't expecting perfection, just something new and in good shape.
I would like to see what comes out next. I am still waiting for my SX-64 themed case which is part of the KS for the 1200 keys.
