I could swear that before yesterday, the standard email app (not Gmail), showed black text on a white background. Now it's white text on a black background. I haven't [knowingly] installed any updates to either the app or to the system. And I can't find any settings to change the color scheme.
Has it always been white on black? What color scheme is your email?
This is a VST (Very small tip) :).
How to run xterm with white letters on a black background, opposite to the default black on white.
This should (IMHO) increase the duration of your laptop battery as less bright is used.
xterm -ls -fg white -bg black
You can create an alias for this command, like this:
alias xtermblack="xterm -ls -fg white -bg black"
The problem with both of these is that the text is displayed in white letters on a very light grey background, and I have reached an age that I can't tell what's there. I would prefer either black text on white background, or white text on a black background. Running Ubuntu 12.04 LTS.
Just got a LG optimus F6 thru T-Mobile. I had a Droid 4 thru Verizon. The droid 4 is set up with black background with either white of blue font. I called LG to see if the Optimus F6 could be changed to the black background with white letters. They said no. They said to get a "DISPLAY" app to do this.
