comment color: # vs. ##

Hi, is there a way to have a different color for line comments beginning with a single # or 2 (or more), ##?

I typically comment out code using single comment characters:

1. if not blah:
   
2.     blahblah()

and use ## to begin descriptive text.

## This code handles blah by doing blahblah.

Specifically, I'd like to use grey for commented-out code and green for informative text.
