My maternal grandma was colorblind, a VERY rare thing for a woman (actually 0.4% chance!)
Because of this, all of her sons and grandsons are colorblind. All granddaughters have a 50/50 chance of being a carrier of the gene (which I am.) Both of my sons are colorblind and my daughter could be a carrier.
At my oldest son's parent-teacher conference I was making sure all the medical stuff was in his record. I asked if they had the eye doc's report that he was colorblind. We started talking and realized that his test scores had gone down in math (which is crazy because this kid can do multiplication and algebra and he's only 7.)
The teacher said, "You know, they are focusing on graphs and charts this year alot on those computerized tests. Would the colors on that effect how he answers?" Well, I got online and started researching. A scientist at the Eye Institute in California told me he was sure it would effect the test outcome.
Maps- First is normal vision, then 3 types of different colorblindness
and how it looks
Look here for how things can look to colorblind people.
"What can we do?" I asked.
Well, we are still awaiting answers. I'll keep you posted. Or, if anyone else has had experience in this please leave a comment!
I talked with my uncle yesterday and he said "You know, I can't read a lot of the things on your blog." I hadn't even thought about the background colors and font colors and how they would appear (or not appear) to colorblind people! I changed a lot last night, let me know if it works guys!
