I found that switching to red filters on my safelights made seeing in my darkroom easier. Except when trying to see red china marker, of course.

My impression is that OC (amber) safelights are apparently brighter but I can see finer details under red. I suspect it has to do with the color receptors in my eyes (and I don't have a clue whether I am normal in this regard).
