Isn't possible to have a board with different color for the bull's eye?
It is. (And I did.) But not yet without adding some JavaScript. I suppose it would be easy to introduce a parameter checkering, to specify a value similar to that of the morph parameter, (it could even be parsed by the same routine), with squares marked L, S, O, or D. Where L would stand for the given lightShade, O for oddShade, S for startShade; all of those being parameters that already exist.
I didn't do that so far, because the Interactive Diagram was mainly designed for functionality rather than beauty.
