AB Browse: Results Column Header Rollover Hard to See

1. Go to http://current.dev.curriki.org/xwiki/bin/view/Main/BrowseStandards?url=/ab/ab/en/browse/al/al-course-of-study/30/243/20877
2. Rollover the Column Header

Problems
1. The Header color change is too light. Can it be closer to the Header color default?
2. The sort arrow is too hard to see on the rollover. See screen shot.
