That's very nice. I like to see people trying to make communication clear and comfortable for everyone. There seem to be so many forces working in the opposite direction these days.
I am curious about how you arrived at the colour choices. Are they based on different types of colour blindness?
The alternate colours are very comfortable as well which I actually find a bit surprising because blues mostly rub me the wrong way. The particular blues which you chose however, are very comfortable. Colour sensitivity is of course a psychological problem, but I am sure that there are many people in the same situation.
Glad you like it . Yes, the colours are based on different kinds of colour blindness.
