PowerPoint slide for the Color Weak (Blind)

Color blindness runs in my family. My Great-Grandmother -> Grandfather -> Mother -> Brother and now my son are all color blind. Color blindness is an incorrect description of the disorder. People with color-deficient vision are not blind to color, but instead see it different. Nowadays, optometrists call it color weak, which is a much better description and more accurate. My 7-year-old son hates being called color blind as he is not blind at all.

How all this relates to PowerPoint is that I often think of how a slide will look to a color weak person. I found a nice article that describes how a slide might look different to the different types of color weakness. The article also suggests using the Vischeck website to upload and view your slide to check it's readability for the color weak. But if you don’t want to go to all the trouble, just stick with the basics and keep your slides simple with contrasting text and you’ll have no problem.
