I wrote a little file-viewer for the VAX, that's able to display 
aa's in different, user-defined colours. Because the VAX doesen't support
colours in  textmode, I performed a REGIS(Graphics)-output. So its 
disadvantages are, that it's working very slowly and it's not an editor.

But the groups of aa with the same colours by default in this Program are

K R H                 kations         black on red
E D                   anions          black on blue
S T Q N               polar           black on yellow
V L I A W F C M Y     not polar       black on green
P G                   "special"       black on white
I think it's better to use a coloured background instead of coloured letters,
because if you want to read the letters, it's better they're in one color.
And if you want to distinguish different groups of aa's, it's better to have
more coloured area than only the letters themselves.

Instead of programming a whole editor for the MAC, I think it would be a good
idea of using a kind of macro with a present word-processor. Does anybody know 
about such a macro-tool for "WORD for MAC" ?
