Why does Crayola and Rose Art make white crayons when no one uses them?

Also, to teach them that indeed white crayon makes little or no effects o white paper. That may seem obvious to you. There is nothing like find things out for yourself, and eventually, it will show on other colors.

A lot of schools used to give kids stuff called sugar paper. It was rough grey paper which came in large sheets or rolls. It was quite thick, and you could glue it together into little boxes and things or try to make friezes out of it and stick them on the walls.

Because other people who do Art, work on brown or charcoal grey paper or even other colors and need to do white at times - like for highlights.
