Notes:
Use white instead of pastel or light colors.
Everybody can see blue.
For some color blind types:
Red = Green
Red = Black
Blue = Purple

If you stick to black, white, and cyan /magenta/yellow like a photocopier, then you should have fewer problems.

• Blues hues are too similar; to greenish-blue or purplish-blue.
• Yellow-green/yellow/gold are easily confused with orange/brown)  
• Magenta/reds and gray can be similar under various conditions.
