Lists and Indices

I would like to write out the (not necessarily unique) contents of a list
with corresponding index numbers. Suppose I have

colors = ['red', 'green', 'blue', 'red']

and I want to see

1.  red
2.  green
3.  blue
4.  red

I currently use

for color in colors:
    print '%d.  %s' % (index, color)
    index += 1

but that does not seem pretty to me; I don't like the "extra" lines for the
index variable.   I could do

for index in range(len(colors)):
	print '%d.  %s' % ( index, colors[index])

but I don't like's not easily readable, IMHO.

If the entries were unique, I believe this would be easy, but how can I do
it with non-unique entries?
