I don't understand what you are asking, since the existing set of applications running in a terminal are able (or could be altered) to choose their own color palettes. Incidentally, since patch #357, xterm has the ability to switch rapidly between palettes (but of course, it'll be "a while" before others copy the feature). https://invisible-island.net/xterm/xterm.log.html#xterm_357 -- Thomas E.
