Color blindness

Being able to distinguish the color purple from the color blue is one way to determine if your child is color blind. The classic Discovery Toy, Hammer Away is in the form of a toy tug boat. It has 4 colored balls for a child to bang on, while they explore cause and effect, hand-eye coordination and object permanence. A byproduct of matching the color of the ball to the color of the ring around the opening is that you'll quickly see if your child is matching purple to purple or purple to blue.
