Text generated by the Message[ ] function is displayed using the Message cell style. This color of this text is governed by the Style Sheet you are using. While editing the style sheet will allow you to change the color of all message texts, there is no straightforward mechanism for making warning messages appear in blue and error messages appear in red. The kernel and the front end do no see any distinction between what you consider a "warning" and what you consider an error. Mathematica's typesetting machinery does allow for the embedding of StyleBoxes (which can alter the color of the text, but not the message label; i.e. Message::tag), but you would need to do this modification for each message text in Messages.m. This would be an admittedly tedious task indeed! If you are wanting to modify your own set of warning messages, then this might not be such a problem. Here is an example of how you might go about doing this: symbolname::error = "\!\(\*StyleBox[\"This is an error message\",FontColor -> \ RGBColor[1,0,0]]\)" Message[symbolname::error] Hope this helps! -- P.J.
