I appreciate that we have color blind settings, but can I offer one way to aid us "challenged" folks?
Red and green are so very hard to tell apart, and the letters help, but still...
If you could default the small number games to blue, red and yellow...well it would be much easier to look at. It is hard to describe how hard I have to peer to see the letters even. Those 3 colors are very distinctly different and easy to tell apart.
Cheers,
Pop
