Oh yes, right you are. If you add the column numbers to the ::set() 
call then the example should work.

This is more of a general GTK+ question than specifically about Vala, 
but just create a model with at least three columns: One for the first 
view column's text, one for the second view column's text, and one for 
the second view column's colour:

Then create the second view column that hools up the cell renderer's 
properties so they refer to the second two model columns:
