An exciting hands-on tool that teaches children about color combinations. By simply rotating the dinosaur's back plates children can use the transparent color windows to visually mix colors. Twelve colors around the outside of the wheel can be combined with five colors on the dinosaur's back, making sixty color combinations possible. It is an ideal accompaniment to a basic watercolor or tempera set, allowing children to create the colors they have combined on the wheel. Suitable for ages 4 and up.
