Thank you, this is great work.

While implementing the UI for a medical device I had the disappointing experience of having to work with a UX company that designed an interface that relied almost exclusively on colors to indicate results and state (red, green, orange, blue, yellow...). When I pointed out that the color blind would not be able to understand their color-based system they refused to make any changes -- not even adding distinct icons for distinct results. These people claim to be UX specialists for medical devices.
