PROMPT works through the environment variable mechanism of PC-DOS.  
Unfortunately, PC-DOS has a *very* small amount of space for environment
variables (128? 256? bytes), and if you have a number of environment
variables set for other things, there may not be room for you to set
the prompt as well.  Better just to create a file with the ANSI color
setting modes in it.  If need be, you can build a BASIC program that
stores the ANSI sequences into a file.  (Note: BASIC can't directly
set screen color with the ANSI sequences --- it's output (annoyingly
enough) doesn't go through the ANSI driver.
