Color Blind Web Sites

I'm now working at Fortress Solutions. The company changed its name at the beginning of the year, and asked me to do a new logo and a new website. We provice repair services for telecom electronics, and we have a web tracking system that displays items with color-coded priorities. One of our customers is color blind, so red and green look the same to him, and I was tasked to fix that.

And a very interesting task it was. I found out all kinds of things about color blindness, and with the help of this color filter I was able to make a new color scheme that makes sense to normal eyes as well as most kinds of color deficient eyes. Here are a couple of charts showing how the service level scale looks to the most common types of color deficiencies before, and after adjusting for the deficiencies.
