Coloring books are a form of adult
therapy that saw a growth in popularity in the 2010s. They reportedly bring people a sense of their
childhood, and help with developing fine motor skills and vision, reducing anxiety and creating focus, and relieving stress and anxiety in a manner similar to
meditation. Concentrating on coloring may facilitate the replacement of negative thoughts and images with pleasant ones. Coloring books can be used in daily activities. The books are also a way to get away from technology, which some may regard as beneficial to people's health. They can also be used by people who aren't as comfortable with other extremely expressive forms of art. The first commercially successful adult coloring books were published in 2012 and 2013, By November it was reported by
Amazon.ca that the books were the most top wished for items with nine of the top ten consisting of such books. Also that month
Crayola began offering its own line of adult coloring books. Publishers also began packaging some of their coloring books with pencils and
CDs to support the enjoyment of this activity. In 2016,
Faber-Castell, a worldwide color pencil supplier, was reported to have trouble keeping up with demand for their products due to the craze, while
Blue Star Coloring sold over a million titles in one year. The scale of the trend in the United States began to decrease by the end of 2016. As of 2025, content featuring adult coloring books were part of the "cozy coloring" trend on
TikTok. Adult coloring books are offered digitally, via ebooks, digital apps, and coloring pages that can be colored online or downloaded. Users' digital work-products can be saved and shared. Dominic Bulsuto theorized that the trend of digital purchasing helped the spread of the genre, noting that the relative anonymous nature of the act allowed customers to feel more secure perusing books they would be embarrassed to buy in real life. She believes the
Great Recession has contributed to this shift, as adults unable to find employment have moved home to live with their parents. New York City
futurist and blogger Dominic Basulto describes adult coloring book fans as "stuck in The Shallows, mindfully coloring books to counter the existential angst of living in a digital society". He goes on to say that "...the endless Internet parade of silly cat photos, infantile comments and adolescent
memes has dumbed us down". However, Basulto ultimately sees the trend as a good thing, noting that adults are increasingly buying books they want to buy, rather than books they are supposed to buy. ==Coloring book software==
