The site has had a very nice upgrade. Pretty graphics and everything. But I am colour-blind and some options are impossible for me to see!
I have to press CTRL-A to "highlight" the whole screen to find the "Add Comment" link, and to read the output of the answers and questions I write. There are probably other options I can't see but have just not yet noticed that they are missing!

Let me know if you find anything else that is hard to read. We’ll fix the ‘add comment’ link.
The summary block on the recent activity screen is difficult to read (light fore and back colours), when I mouse-over other people’s comments (maybe for vote up) the text disappears (light fore and back colours), one of my questions has more than a 1000 views and I can’t see the 1K number (dark fore and back colours), and when a question has 0 answers I can not see the zero (dark fore and back colours).
Hovering over comments is also dificult to read. Light gray text on slightly darker background makes for very little contrast.
A new set of changes has gone in. Can you review and see if we’ve missed anything?
I can not find a question with zero answers, so I can not test that change just now, but all the other changes are excellent and work well. I can not find any other areas that might need colour changes.
When editing a post, the link to go back is black on black bacground.
