Heidi Cool posted a reply on Quora today to a question about Web accessibility.
One of the sites she referenced in her reply was a colour blindness simulator.
I thought I would try the simulator using an image that has a lot of blue in it.
Here’s the original image, followed by a screen grab of how the simulator suggested a person with that particular sight deficiency would see it.
Of course, if you suffer from this deficiency, I am not sure how it is going to look to you.
What I know is that after seeing the red yolks, I have sympathy for anyone who has this deficiency. But maybe my sympathy is misplaced? After all, I have no idea what the reaction of such a person would be to red yolks.
Perhaps they don’t seem ‘red’ at all. What would the reference be? How would a person born that way be able to communicate meaningfully with a ‘normal’ person about their reaction to such colour perceptions?
It’s a mystery.


If you are interested in other aspects of Web accessibility, here is Heidi’s complete answer to the question.
