Almost any RGB colors you want that can be programmed on the chips! YES PLEASE! Of course, the program cannot handle like 12.8 million color choices like those RGB keyboards out there, but I think in due time, it would be able to. Since it'll all in the programming and that has been updated like 3-4 times already in the short span that I have had my chips. I think they are doing an amazing job interacting with the customers on facebook page and helping anyone and everyone! I personally haven't posted any questions on there, but reading other peoples questions (usually the same as mine) I was able to fix many problems.
