Add an option for color blind operators to change the colors of notifications or statusses

I'm red / green color blind, like 10% of the males.

I'm not able to distinct the online status color (green) with the offline status color (red). 

It is hard / impossible for me to see if a user is still online (green dot) or offline (red dot). I'm also not able to see if I'm online (green dot) or Away (red dot).

For the browser version I was able to inject custom css for this. I changed the red color to blue. But I'm not able to do so in the Android app for example.

It would be very convenient to add a color blind option to change the color scheme.
