Colors and More Colors!

[Scott Williams]

Whne someone uses colored fonts, they get scored like:
 
 0.1 HTML_FONTCOLOR_RED     BODY: HTML font color is red
 
or
 
 0.1 HTML_FONTCOLOR_BLUE    BODY: HTML font color is blue
 
 
Some HAM I have is in a font color(some people JUST have to stand out), but 
rarely does HAM have multiple colors.
 
Is there a rule out there someone can share that penalizes in MORE than a 
linear fashion
for spammers using a number of colored fonts?
 
ie:   2  colors used  score    .5
        3 colors used score   1.0   etc
 
Thanks,
 
Scott
