Not true.  A color file will get squashed to gray scale by most 
publishers and many colors render very poorly when printed that way.  I 
have been bitten by printing and having it come out color.  If you print 
black and white and display it on a color device, you won't be wrong but 
if you print color and print on a black and white device (e.g. laser 
printer), you may not catch the error until the book comes out.  Of 
course, these are all specious arguments since I can't imagine 
publishing without checking such things.


This is really a tempest in a teapot folks.  No matter what you pick it 
will be right for some, wrong for others.

Do it the way MATLAB does it or don't change anything at all.  Of course 
the person writing the code probably gets to do it his/her way!
