Isle Royale Forums

I recently changed my phone's settings to switch to grayscale when I plug it in to charge at night. Although I can easily tell what threads on a board have new posts---it has a small icon---from the main page, I can no longer tell what boards have new posts. The usual blue vs red icon all looks the same (same shade of gray). Is there some way to adjust the saturation of one of those colors so they appear as different shades of gray, or use an icon on the main page as well?

Thanks.
