Have your import hook inject the necessary import statements at the top of
the generated code:

    generated_code = """from Color import Color
                        %s""" % data

Here I put your Color class in a file named Color.py.

Now when I run the script testColor.py, which contains this code:

import Colors
import abc

print abc.c

I get:

from Color import Color


c = Color(255, 0, 255)

cols



Now the last step is for you to convert your assignment to generated_code to
use a pyparsing expression, and call transformString on the content of the
file (in your variable 'data').
