Ok, I'm typing this during a bout with the flu or a cold or something, 
and colors are swimming in my peripheral vision, so take this 
explanation with that in mind....

The face.col attribute returns a tuple of MCols and takes a list or 
tuple of MCols.  There is no constructor for MCols, so right now the 
only way to assign MCols to a face is to read the existing values, then 
change them:

cols = face.col
for col in cols:
     col.r = 0

If you want, you can also just set them directly:

face.col[0].r = 0
