Japanese Maples: ID for new tree?, 1 by SongsofJoy

I'm hoping for an ID on a bonsai palmatum I received recently as a gift. The owner of the nursery from whence it came does not know the variety. I realize it could probably be one of several possibilities, but I figured it couldn't hurt to try. Earlier in the spring, the leaves were predominantly an apricot color. Now the leaves are more chartreuse with orange/red coloring along the edges. The leaves are small - probably 1.5 to 2 inches max.
