The phrase represents a specific type of arts and crafts activity. It involves a pre-printed canvas or board divided into numbered sections, each corresponding to a particular color of paint. The goal is to apply the correct paint to the corresponding numbered area, gradually revealing an image of a pink wading bird. As an example, a kit might include a canvas pre-printed with an outline, several small pots of acrylic paint each labeled with a number, and paintbrushes.
This activity provides an accessible entry point into painting, requiring no prior artistic skill or experience. Its appeal lies in its stress-reducing nature, encouraging focus and mindfulness. Historically, this form of art has been a popular pastime, offering a sense of accomplishment upon completion and resulting in a tangible decorative item. Its accessibility and predictable outcome contribute to its lasting popularity.
