Alexander Calder's collaboration with Braniff International Airways in the early 1970s to create the "Flying Colors" series marked a fascinating intersection between avant-garde art and commercial aviation. In 1973, Calder was commissioned by Braniff to celebrate its 25 years of service to South America, leading to the creation of a distinctive livery for a Douglas DC-8-62 airplane. The aircraft, named "The Flying Colors of South America," showcased Calder's bold design in primary colors, featuring his signature "Beasties" on the engines, a touch that added whimsy and charm to the design. Calder's participation in the painting process and attention to detail ensured that his artistic vision was faithfully executed on the aircraft, which made its debut at the 1975 Paris Air Show​ (Design You Trust)​.

Following the success of the first plane, Braniff commissioned Calder for two additional aircraft, both Boeing 727s. One of these, completed in time for the 1976 Bicentennial, was named "The Flying Colors of the United States" and featured an abstract rendition of the American flag. Unfortunately, Calder passed away before he could complete the third aircraft, "The Spirit of Mexico," leaving the "Flying Colors" series as a memorable legacy of his foray into the realm of commercial design​ (Design You Trust)​.

The "Flying Colors" project was emblematic of Calder's multifaceted artistic practice, which spanned sculpture, painting, jewelry design, and even theatrical sets and costumes. Beyond the visual impact of the liveries, the project reflected Calder's lifelong fascination with movement and his belief in art's accessibility to a wide audience. The brightly painted planes not only served as flying canvases that brought Calder's art to the skies but also underscored the potential for collaboration between art and industry, allowing millions of people around the world to experience an original Calder​ (Something Curated)​.

This innovative project between Calder and Braniff remains a celebrated example of how art can transcend traditional boundaries, merging with everyday life in surprising and joyful ways.
