Paint by number looks like a modern invention, but its core idea — splitting an image into zones and telling the learner which color goes where — is centuries old. This is the story of how a Renaissance workshop trick became a mass phenomenon in the 1950s, survived the art world's disdain, and ended up in the palm of your hand.
The precedent: Renaissance workshops
In the great masters' workshops, a painting was rarely the work of a single person. The master designed the composition and apprentices executed specific sections under his instructions. Leonardo da Vinci is said to have assigned his assistants numbered sections of his works so they could work on them independently. The underlying idea — separating design from execution so someone without the master's skill can still take part in the result — is exactly the same one that makes a paint-by-number kit work.
1950: Detroit, industrial paint, and a business idea
Paint by number as we know it was born in Detroit, at the Palmer Show Card Paint Company, a paint business run by Max Klein. One of his employees, commercial artist Dan Robbins, was looking for a way to sell more paint to hobbyists and remembered the Renaissance workshop technique. His pitch: sell a pre-drawn canvas with numbered zones alongside numbered paint cans, so anyone could complete a "real" painting without knowing how to paint.
The first kits, under the Craft Master brand, hit stores around 1951. The slogan said it all: "Every man a Rembrandt." After a slow start, the product exploded: by the mid-1950s, millions of kits had sold in the United States, with subjects ranging from landscapes and seascapes to horses, kittens and religious scenes. For a while, it was said that more "paint by number" paintings hung in American homes than original artworks.
The controversy: is that art?
Success brought criticism. For much of the art world and cultural press of the time, paint by number was the perfect symbol of postwar conformism: canned culture, mass-produced creativity, the very negation of what art was supposed to be. "Paint by numbers" became a derogatory expression for anything mechanical and soulless, a usage that still survives in the language today.
The defense, then and now, is the obvious one: nobody claimed to be creating original art. Millions of people who would never have touched a brush spent hours mixing colors, learning composition by osmosis, and discovering they enjoyed painting. Many amateur artists (and some professionals) started exactly there. Robbins himself summed it up by saying his invention didn't teach people to be artists — it opened a door that was closed to most.
The redemption: from the attic to the museum
Over the decades, nostalgia did its work. The paintings that had decorated 1950s living rooms moved on to flea markets, then to collectors, and in 2001 the Smithsonian (National Museum of American History, Washington) dedicated an exhibition to the phenomenon: "Paint by Number: Accounting for Taste in the 1950s," which treated those kits for what they were — a first-rate cultural document about postwar leisure, taste and the middle class. Dan Robbins passed away in 2019, by then recognized as the father of a global hobby.
The digital era: from canvas to screen
The leap to screens changed the rules. Color by number apps — which really took off from around 2016-2017, riding the wave of adult coloring books — eliminated the two classic frictions of the physical kit: materials (paints, brushes, space, drying time) and error (digitally, it's impossible to go outside the lines or run out of paint). In exchange they gained things impossible on paper: infinite zoom for small zones, saved progress, hints when you can't find a zone, and the ability to share the result instantly.
The first generation of these apps repeated the kit model: catalogs of pre-designed sheets (mandalas, animals, scenes). The second generation — which Color Memories belongs to — adds the missing ingredient: making the image your own. Instead of choosing from a catalog, you upload a photo (your pet, a trip, a loved one) and an algorithm turns it into a unique numbered picture. If you're curious how that conversion works under the hood, we cover it in from photo to picture: how it works.
What's stayed the same after 75 years
The curious thing is how much hasn't changed. The 1951 kit and today's app sell exactly the same thing: the promise that anyone can finish a picture they like, the calm of a structured manual task, and the small satisfaction of watching an image emerge zone by zone. Technology has only removed the obstacles. Even the controversy remains the same — is it art? is it creative? — and so does the answer: it's something else, an accessible hobby, and that's enough. We talk about the real benefits of that calm in why paint by number relaxes you.
