Long ago I did some UI design for the military, the only job I've ever done where I had to account for colorblindness. The main thing was just never to use color alone to indicate anything. It's OK to have color enhance the distinction between elements, just not to be the only distinction. What worked best was just to design the UI in monochrome and then add color to make things pop. I've found it to be a great principle to carry forward since it improves usability for those with or without full color vision, in all kinds of lighting scenarios. (I realize this doesn't really answer the question, which is an interesting one. Just suggesting it may be solving the wrong problem.)
