This free app includes two activities to help children learn colors - red, green, blue, orange, brown, purple, yellow, white, and black. The first activity allows your child to press color buttons to hear the name of the color, see the spelling of the color, and see an animal with the associated color. The second activity provides a basic progressive quiz to help your child test their knowledge. (The full paid version includes two additional activities and another set of "advanced" colors to learn)
