The image is a simple, black and white line drawing intended for kids to color. The main subject of the picture are the 'Rainbow Friends' who are stylized, childlike characters, standing under a large arching rainbow. The peculiar aspect is that the rainbow is suggested to be purple, yet it is drawn with outlines only to let kids fill in the colors. The design of the image is very friendly and fun, with the characters displayed variously smiling, waving, or holding hands. The background includes light sketch of clouds and sun to complete the cheerful mood. Large, open spaces have been left untouched for the children to fill with their favorite hues, avoiding any excessive black fillings to maintain its simplicity and appeal to young colorers.
