jfuller, most JMs burn their leaves during the first summer because the roots are not established. You are correct that its coloration will be different next year. Amber Ghost along with several other Ghost maples have a lot of differences in color and leaf size from year to year. Peaches and Cream also tends to vary from one spring to another, but when it is right on - it is indeed Peaches and Cream. I don't think that having much less sun will affect your Amber Ghost. I like the more subtle shades like pink, lavender, and light green.
