Create colorful art without the mess! Crayola® Color Wonder™ Magic Light Brush lets kids create amazing mess-free art in a magical way. While Color Wonder paints are clear—and therefore won't mark or stain furniture, carpet or skin—the color magically appears when applied to the special paper. But kids don't need to know the color of clear paint because the Magic Light Brush lights up in the color of paint they're using! It changes color from blue to green to red whenever you change paints.
