1. In the image you can see that the hyperlinked text "Return to Assessment List" is not aligned properly. It is more apparent because the Instructor chose to change the background color. I think the item should also inherit the background color. http://www.screencast.com/t/YTwsg41igO
2. Since the Instructor doesn't have the ability to change the highlight text color, this creates a new kind of ugly. Potential fixes include:
a. Changing the highlight to be black background with white text (so it would be static and display against the normal white background).
b. Invoking a web color palette engine to pick a color in the same palette as whatever color they choose for their background. Some generators use the hex color, some use images http://www.colourlovers.com/palettes/search or http://www.pictaculous.com/ etc. Here's a node.js version with an API: https://github.com/tj/palette
