In my opinion, the new pot is still too big and the color does not accent any part of the tree as far as I can tell from the picture shown. The old pot was much closer to a color that would compliment the flowers in bloom, which is the prime time to display this species. Well, maybe a tad bit more green and a little less blue. At any rate a complementary color should be used to highlight a good feature of the tree, in this case, the flowers.
The tree itself is obviously still under development so any critique would be premature. It does have one heck of a big trunk though.
