Do you mean the first film made on color film, or the first film to have color? The generally accepted answer to the first film shot in color was Cupid Angling made in 1918, the Wizard or Oz and Gone With The Wind were made in Technicolor in 1939, a process that had been around for quite some time by then. There were hand colored segments in movies dating back to 1902.
Gone With the Wind was widely praised as a landmark achievement, and critics continue to regard it as important for its cinematography, art direction, and special effects, and for its ambitious portrayal of history.
