This tool reproduces your images under various forms of colorblindness so you can better determine if your reporting will be readable to those who are colorblind. 

"Vischeck is a way of showing you what things look like to someone who is color blind. You can try Vischeck online- either run Vischeck on your own image files or run Vischeck on a web page. You can also download programs to let you run it on your own computer." (Dougherty & Wade, 2008)
