I'm mostly a lurker in this list, but on this one I want to put in my two
cents. Specifically, I think the concept of relative colors is a WONDERFUL
idea, and one that would make my life as a designer MUCH easier. PLEASE
give serious consideration to implementing this! Or share your browser code
with me and I'll give implementing it a shot. This just plain NEEDS to be
