I’m not sure you actually intended to reply to me but my original remark was wondering why a question about mechanical keyboards would be limited to use with a Mac Studio vs. any other computer model. It’s not as if the Mac Studio makes a keyboard perform any differently.I'm assuming that the colors are Cherry MX key colors.
Blue is clicky.
Brown is tactile and non-clicky
Red is non-clicky linear
Green is like Blue but requires more activation pressure and there's more acoustic feedback
