Causes of Colors – Why are things colored?

Everything you ever wanted to know about color. I found the bits about color blindness to be very interesting. When we design programs and web pages, we always have someone with severe red/green color blindness use the program to make sure it’s readable to him.

There are a couple of web sites that allow you to upload images and view them as they would appear to someone with color blindness. Try this one and that one.

When I was growing up, one of my friends that lived down the street had red/green color blindness. He would come out to the bus stop wearing strange color combinations. We would send him back in to pick other clothes. I assume that these days, his wife gets that task.
