Re: A test for Color. Please comment.

I don't think the dev's should be responsible for ANY random override. I
think they should be responsible for demonstrating one override of their
choosing.

The random test here might pass, but another random one might not. How can
a dev demonstrate he conforms with the SC. If they do 100 of these random
tests, 2 might fail. If they do 1000, 10 might fail. There is no end to the
responsibility, and risk for them.

Cheers,
