LED indicator considerations for colorblind users?

I'm working with some hardware that has RGB LEDs to indicate various states. The LEDs are limited to each element being fully on or off, so there are effectively 7 lit states (R, G, B, RG/yellow, RB/magenta, BG/cyan, RGB/white). If I want to consider (red/green) colourblind users, do I need to consider R and G as being the same LED (i.e. R=G=yellow, and magenta=cyan=white)? i.e. only use 3 possible lit states (R, B, RB/magenta)?

I'm only considering colours at this point; flashing is already being considered.
