Colorforms, invented by Harry and Patricia Kislevitz, refer to a general type of vinyl adhesive toy set produced under the Colorforms brand.
Colorforms are paper-thin, die-cut vinyl sheet images and shapes that are meant to be applied to a shiny plastic laminated board, much like placing paper dolls against a paper backdrop. The images stick to the background by adhesion, which takes place when two highly polished surfaces come in contact. The Colorforms vinyl pieces can be repositioned to create new scenarios.
Founded in 1951, Colorforms is one of the oldest and best-known brands in the toy industry. It was the very first plastic-based creative toy, and one of the first toys ever advertised on television.[dubious ]
The original Colorforms sets were assembled by Harry and Pat Kislevitz, themselves, in their New York city apartment. Boxed sets began appearing in the 1950s and featured basic geometric shapes and bright primary colors. The company used the slogan "It's More Fun To Play The Colorforms Way!" in print ads and television commercials to promote their products.
The defining feature of most Colorforms play sets is their signature plastic ‘Stick-Ons™’that can be placed and repositioned on top of graphic backgrounds to create endless scenes at a child's whim. Over time, the Colorforms line has included imaginative play sets, games and puzzles, interactive books and creative activities for young children.
Since its inception, more than 1 billion Colorforms play sets have been sold. Colorforms has more than 75 toy products in current distribution.

Adhesion and repositionability are the elegantly simple concepts behind Colorforms' success. Harry and Patricia discovered this when a friend who manufactured pocketbooks gave these two art students a roll of flexible paper-thin vinyl. The Kislevitzes discovered that the vinyl stuck to the semi-gloss paint in their bathroom, and began cutting shapes out of the material and placing them on the wall. Having fun with the process, the Kislevitzes left extra material and a pair of scissors out for guests to add to their creation. Based on the concept's success, the Kislevitzes decided to market their idea as a consumer product. Originally targeting other artists and adults, the product quickly became popular with children and the Colorforms brand took hold.

Licensed Characters 
The first licensed character product was released in 1957, featuring Popeye. Since then, Colorforms has continued to expand its licensed character agreements, with dozens of brands connected to Colorforms.
Later Colorforms licensed various properties, producing box sets supporting various cartoons, TV series and movie releases, including Peanuts, Tarzan, The Three Stooges, Doctor Dolittle and Chitty Chitty Bang Bang. In 2011, the 60th product anniversary year, Colorforms added Green Lantern, My Little Pony, The Gruffalo, Tonka and Transformers, among others.
Colorforms products have expanded beyond the simple "paper doll" concept to more than 75 Colorforms toy products currently in distribution, with more added every year. The Colorforms series later expanded into cartoon character sets such as Popeye and Gumby and original character sets on household themes such as Miss Weather, a girl whose wardrobe changed with the weather, and Miss Cookie's Kitchen, a woman with a variety of kitchen tools and utensils.
Other products 
The Colorforms Corporation also produced Shrinky Dinks, The Outer Space Men bendy action figures (1968), Dress-Up Sets, and Monster Print Putty. The latter, which was boxed in a skull-shaped plastic shield for a heightened "monster" effect, was a pliable clay-like substance that picked up newspaper-ink images when pressed upon them, similar to Silly Putty, except that Monster Print Putty could then transfer those images onto a special "Monster Print Paper" when applied to it.
Colorforms acquired the rights to license and distribute Shrinky Dinks in 1981, and continued creating and promoting their products until the brand was sold to Milton Bradley in 1989.
