Crayon is a pen made by mixing pigments in wax. It can have dozens of colors and can be used for drawing. Crayons are not permeable, they are fixed on the screen by adhesion. They are not suitable for overly smooth paper and board, nor can they be used to obtain composite colors by repeated superposition of colors. It is an ideal tool for children to learn color painting. Some painters use it to sketch and record colors.
