The typical answer is "start it with a private colormap". Programs
like Netscape and occasionally Emacs and definitely "pretty" window
managers are known to eat up colormap entries, and with an 8-bit
display you only have 256 of them. Many programs that support private
colormaps have a -private or equivalent option you can use to get
around this.
(If you have the video RAM, you're almost certainly better off using a
higher-bit-depth display; I think there are very few programs that
aggressively demand a PseudoColor visual. Some things, like video or
3D rendering, might demand a 16-bit display over a 24-bit one.)
