Charlot went to Colorado Springs, Colorado in 1947 to take a job at the Colorado Springs Fine Arts Center, where he taught fresco painting and worked with Lawrence Barrett on several editions of lithographs. While there he also taught art at The Fountain Valley School, an independent school for boys (at that time), founded in 1930. Charlot left the Fine Arts Center in 1949 under a cloud of misunderstandings between himself and the Arts Center's Board or Trustees and the Art Center's director, Mitch Wilder. Charlot then went to teach at the University of Hawaii, where he stayed for over 30 years. There, he developed a close friendship with the world-famous local artist Madge Tennent and collaborated with Juliette May Fraser, an accomplished muralist in her own right, on several major commissions in and around Honolulu. During the summer of 1969, Charlot worked with Tony Smith at UH and Smith thanked him by creating a piece in the "For..." series named "For J.C."
