I really could not get your question. If you are asking that how to save matlab figures in colour then when you are saving file in your m file, lets say in post script format then use "-dpsc" here "c" is for color.
The second way is to go matlab prompt and just type "help print" or go to "print doc reference manual" in matlab help.
I m not sure whether i helped you or not, if not please specify your question a bit more.
I dont know even if there is any thing like that. I mean this color stuff, i never need it actually, though i m working with matlab since quite a long time.
If some one else know this. plz share will be valueable. I will try to find the answer by myself as well.
I saw similar questions in comp.soft-sys.matlab, and the answers were all negative - no way to colorize your Command Window text. However, MathWorks is considering it for a future feature.
You can change MATLAB's overall font and text/background colors in the Preferences menu, but that's not something you can do line-by-line in your program.
