I'm pretty sure that coloring of a near perfect base is something different than color because of lack of a good base.
Artists often deviate from their academic perfected base, so they have a grounded scaffold from where to execute artistic freedom, this cannot be mimicked by someone skipping the base drill. Not in writing, painting, music making, ..... and music reproducing electronics, imho.
That said, my Burson 3XP soloist ain't coloring Chord well to my taste, the Rebelamp does a nicer stroke of coloring, listening a lot un-colored pure Chord output though.
