   There's also the factor that continuous exposure to blue visual field   
   is reported to be more of a mood depressant that other colors.   
      
   Single data point:   
      
   I do most things other than web browsing in emacs:   
      
      emacs -fn [snip] -fg rgb:f/c/c -bg rgb:5/0/1  -cr SandyBrown   
      
   which is (or looks like) white on a dark red background with an orange   
   cursor.  Arrived at this as most readable and least fatiguing after   
   experiments with numerous color combinations incl blues, greens,   
   orange and black background.   
      
   I use vividly different colors for xterms/emacsen that must be easily   
   and noticeably different to prevent bad errors, e.g. su to root or   
   remote logins to ther hosts.   
      
   White background is too bright, too fatiguing.  PDF manuals that force   
   white or bright background are really annoying.
