Craft colored paper, referred to as "colored paper" for short, is the general name of a white signature board, with a common size of 24cm×27cm. The popular colored paper collections in Japan are basically based on the works of famous illustrators, original paintings, cartoonists and original cases.

Craft colored paper is mainly used for drawing characters and signing. In addition, the general circulation of colored paper mainly includes straight signature colored paper (because there is only one piece each, which is rare and very expensive) and carbon paper colored paper (signature to pattern are printed matter, which is mostly used for various special gifts and sold at different prices).
