Of course, some colored film or 'gels' would be much cheaper and just as 
handy.

Guessing you want glasses that null the offending colors -- purple absorbs 
green, making green look black (in the most common red-green 
colorblindness).  Presumably, cyan would also work (complement of red, 
making red look black instead -- so don't mix up your cyan and purple 
'shades!).  It follows, you want the complementary color for whichever 
type of colorblindness you have; the other kinds, being rarer, presumably 
have rather expensive glasses for them, making the cheap solution all the 
more handy.
