Update list of WDN colors

I did. I tried not to get too carried away with the number of UI colors when I created them, and now, of course, I need something in between ui07 and ui08. There may occasionally be these instances where a certain color that is not in the UI color list is needed, but I think using a UI color as its source helps. 

I'm open to other approaches, though—or, revising the list if necessary.
