Seattle's apple orchards suffer from tree pests called apple maggot and coddling moth which can be prevented by covering young apples with nylon "footies." For Blushing Orchards, the footies were dyed in rainbow colors with food-safe dye. Based on color theory, each hue is intended to illicit a different mood. As people walk along the trees, they might notice how each color makes them feel. Four orchards participated in the installation, Danny Woo Gardens, Magnuson Community Orchard, Seattle Tilth Learning Gardens (here) and Bradner Gardens Park. Orchards stewards and volunteers who participated reported that it was more fun to work with a variety of colors than the typical beige.
