Nice!I just do not understand why colors has the same size as the nodes collection. It should have the same size as the max nesting level. What do I get wrong?In any case, I think for shading we need also strategy that hides the implementation details (so, no explicit color creation). I think that we can just give a min and a max and then simply use a linear color normalizer internally. Of course, we also need a way to marry such an implicit strategy with the possibility of custom colors :).
