One of my favorite book apps! This simple story about colors has the perfect amount of interactivity. There is no spoken narration, but the printed words are available in English, French, Spanish, Magyar and Japanese. The pictures support the text and reinforce the storyline and the interactions lead kids through from beginning to end without distracting from the flow of this simple tale. The sound effects also support the storyline (e.g. while the rest of the colors make a chiming sound when you tap on them, Red (who feels ill) makes more of a honking noise, as though he has a stuffy nose) and emphasize the emotional response to the action. One fun little detail is that the colors, arranged in rainbow order, sound a full octave if you tap on them in order (don't miss out on the little invisible dot at the end of the line!) and if you're musically inclined, you can play a song on them like a xylophone. Great choice for sharing together on your next sick day.
