I thought about making a new shade of the previous icon, but to be honest, I just hated that. It wasn't clear what it even meant unless you read the legend at the bottom of the forum index page, and the basic style wasn't intuitive at all. Ideally, that kind of thing shouldn't need a legend. You should understand just by looking at it.
These are actually more informative than before in that there is a new icon that describes exactly what is "new." Before, it would be green if there were new posts on the main board or a sub-board, and dark gray if there was no new posts at all.
Now, it shows a faded pair of blank paper for no new posts, a regular, non-faded pair of papers for "new posts on sub board but NOT main board," and a regular pair of papers with scribbling (for text) to indicate new posts on the main board.
This looke better and more "modern" than before. Good work!
