Colorful [print]

Hi Maxers,

I'm looking for a way to print a message in the Max window but with a custom line-background color. To produce the same effect as would a Max-error (red background in the Max window) or a Max-warning (orange background) or some strange unidentified (from me) messages which appear sometimes with blue background (can't reproduce right now but if I remember correctly, the last time I saw it, it was something about zget_fn or something like that).
Anyway, do you have any idea on how I could get a colorful message in the Max window ?

Cheers
