Make sure everyone can see your figures

A popular comment to make when critiquing other people's presentation is, "you know people who are color blind cannot read your figure". One way to quickly avoid this comment is to not use red/green to distinguish between data points on your figure. Another way is to check your figure using Vischeck. Vischeck not only checks for red/green color blindness, but also blue/yellow color blindness (Tritanope) and a less common red/green color blindness (Protanope). If you do not know if you are color blind, google "Ishihara Color Test".
