Sorry we haven't responded to this sooner.

I think there's too much duplication of code. We should probably pull the try/finally block into its own method, maybe a context manager, since that code is the same in three places except a few variables. Then maybe we can do something like:

with self.query_response(query_str, response_re, timeout) as match:
    if match:
        return tuple(int(val, 16) for val in match.groups())

return -1, -1 , -1

I rebased and consolidated the common code. Then I noticed all the test data was ffff/ffff/ffff, so I used somes X11 colors instead to make them in range and different values. Out of range values still work, but I don't think it's our place to police that. If the terminal wants to report the values higher than 255, I don't think we care.

@jquast, I think this looks ok to merge. Can you take a look?
