Color Blind?

Color blindness is a form of vision impairment and is covered by ADA. According to the EEOC, "...approximately 10 million people in the United States are blind or visually impaired."

How does this affect us in online education? Obviously at some point we will have a color blind student, and it is our responsibility to make sure the colors and graphics in our classes can easily be read by them. This is where Vischeck can be helpful. This free service allows you to upload a file and see what that files looks like to a color blind person.

The original image shows you a PDF file that I use in my class for evaluation, but the Deuteranope Simulation shows you what my file looks like to a person with red-green color blindness, or Deuteranope. Taking into consideration color blindness when preparing files is also a great way to practice UDL (Universal Design for Learning) principles.
