I don't think such a radical change is warranted, especially since a
large class of tty-like terminals (xterm and its ilk) use bright,
usually almost white, background.

I think this is impossible in practice.  Many proprietary X servers
define lots of their private color names.  There's no way we could
track all of them all the time.

If you want maximum portability, use the "#RRGGBB" notation instead of
a color name.  tty-colors.el supports that (as well as the
"rgb:RR/GG/BB" specification).
