This hands-on tool teaches children about color combinations. By simply rotating the dinosaur's back plates, children can use the transparent color windows to see what happens when colors collide. Twelve colors around the outside of the wheel can be combined with five colors on the dinosaur's back. It is an ideal accompaniment to a basic watercolor or tempera set (sold separately), allowing children to create the colors they have combined on the wheel. "Hue" the Dinosaur is both instructional and fun!Details: Up to 60 color combinations Hands-on tool For ages 4 and up
