Is it just the icon that shows if a thread is new, or all the icons? I like them the new icons but I agree that the new post icon lacks contrast with the standard icon.
I've spend the last few weeks tidying up small niggly bits all over the website. If there's anything people would recommend fixing / changing please let me know. I'm also trying to track down broken links and missing images. If you find any please let me know by email or posting here.
