Why not simply designing a few colored fonts for the mac, where some
letters are assigned background color. Each one could have a name
informative about the coloring scheme: "AA Hydrophobicity" or "AA size" and
the like. Then, using one's favorite editor, you simply select the portion
of sequence to be color-coded and apply the desired voila!

Such a thing as already been done: the font BKGCuclc is the best example (I
don't know where it comes from!!) and is VERY useful to view DNA
alignements, for example in the PAUP editor.
