Rainbow Pen

Rainbow Coloring Tools, a coloring game featuring pictures of animals and magical crayons that can color in regular color, glittering colors, and classical patterns. An additional feature is the ability to increase or decrease the size of the picture, making it easier for you color in more detail. As with most coloring games, there is a magical eraser that can erase all colors while keeping the picture in tact available for you to use to undo your mistakes.
