I searched for some information about presentations for color blind people and found a great article by two Japanese researchers who are themselves color blind.
Here are some interesting points:
- If you have a red-green color plot, change the red to magenta. Magenta is a combination of blue and red, so color blind people will be able to see the blue part.
- It is easier for color blind people to see green laser pointers than red laser pointers (same is true for normal people, too!)
- Fig 16 of the article shows a good color palette that is clear to people of all color-seeing types (whether normal, red color blind, green color blind, etc).
