A comment by nezinscot in another thread about colorblindness reminded me of this discussion. While we already have the ability for users to specify QS parameters to replace the colors to their own liking, it's not especially easy to use and I bet almost no one does. I would like to add support for multiple, well thought out color schemes that could easily be selected by users via QS parameters and saved in cookies or by some other TBD mechanism. Of course, this requires some work on the web front end to support it, but also requires some effort to come up with a collection of good color schemes. Anyone interested in taking this on?
