My wife recently observed my two-year-old son eating green strawberries and is now curious if he has some kind of red-green color blindness. Unfortunately, he is not yet able to give us the name of numbers, so the commonly used Ishihara test images won’t do. Well, I thought it´s a nice idea for this rainy Sunday afternoon to generate some of those images myself. Instead of numbers I used simple images of things I knew my son is able to name. If you like, find the source files here. The icons are taken from thenounproject.
