Because those calls issued by realmode apps won't be going through
DPMI, in the first place. To do what you want, you'll have to hook int
10h in a TSR program and block all calls that would change the text
colours. And even then, you'ld still be fooled by programs that
directly write to the textmode framebuffer (i.e. all programs using
direct lowlevel I/O).
