Excellent summary and examples - especially appreciated the animation showing how to navigate the interface!
As a practical note, I recommend not leaning too heavily on color to provide meaning - color-blindness is more common than you think! Bold, italic, and underline provide more generally readable visual cues.
I have a friend that has Green color blindness which is frequently accompanied by a bit of Red color blindness. I was interested in what he saw or, rather, what he could not see. It turns out that about 1 in 12 men have some form of colorblindness as do about 1 in 200 women. Some of the more interesting facts are here...
If you want to actually "see" what they see, have a look at a link for that page.
I have some work to do but I'm pasting the charts from some of my presentations in it and using it to help me pick better colors and even to combine markings with colors to make things more useful (and visually pleasant) for both those with and without the more common forms of color blindness.
