Online puzzle Paint by number
Paint by number or painting by numbers describes kits having a board on which light blue or gray lines indicate areas to paint, and each area has a number and a corresponding numbered paint to use. The kits were invented, developed and marketed in 1950 by Max S. Klein, an engineer and owner of the Palmer Paint Company of Detroit, Michigan, and Dan Robbins, a commercial artist.
In children 's activity books, some simple activities are often presented to children that are called color by numbers. When Palmer Paint introduced crayons to consumers, they also posted images online for a " Crayon by Number " version.
