Color Wonder is a mess free coloring product by Crayola. It is mainly created to make coloring more fun without the mess which is very common with younger children. Color Wonder was first released in the public in 1993. The first products that they introduced were the Crayola Color Wonder Markers and Crayola Color Wonder Paper, and soon after they also released other Color Wonder products like coloring books, paints, stamps and finger paints. The way it works is by using a special clear ink that will only show up on their specialty paper. The Color Wonder Markers will not work on ordinary paper, cloth, skin, etc. The reason for this is because the Color Wonder Paper contains color-triggering compounds that help develop the leuco dye on the markers.
