But that's the most white color that your terminal can produce.
xterm.el doesn't _tell_ the terminal what color to produce for
"white", it only _documents_ (sort of) what that color is, in terms of
RGB components.

I don't think you can, not for the background.  But I'm not an expert
on xterm.

> I guess I can try and hack my xterm.el

I don't see how you can, but let us know if you find a way.

I'm closing this bug.  Feel free to reopen if you find a way of making
your white "whiter".

Subject: 23.1; white background is color #e5e5e5 in terminal window

I am running emacs in an Apple Terminal window while ssh'd to a Linux Ubuntu 10.04.1 system. My TERM is set to xterm-color. (Note that the Apple Terminal app only supports 8 colors.) All the colors are quite dingy looking, but in particular the background is color #e5e5e5 which on my computer is fairly dark and makes the text hard to read (particularly cyan or green text). 

Here's what list-colors-display shows:

black		       black								     #000000
red		       red								     #cd0000
green		       green								     #00cd00
yellow		       yellow								     #cdcd00
blue		       blue								     #0000ee
magenta		       magenta								     #cd00cd
cyan		       cyan								     #00cdcd
white		       white								     #e5e5e5

Note that others on the emacs mailing list have been able to reproduce this problem (even on a Windows system). See the thread "white is #e5e5e5" started Jan 23, 2011.
