I was going to suggest an acer palmatum of some kind but I thought they didn't like windy positions and need somewhere sheltered.
Not my tree below, but I had one in a large pot for years (and it always looked healthiest in shade) I finally planted it into the ground 3 weeks a go in a shady border.
Leaves are orange in spring, green in summer and yellow in autumn.
Wind kills them really fast so ignore my original suggestion. How big is the pot?
You'd still need a very large pot.
