The Kathe Sandler Collection contains 16mm film and sound outtakes, original negatives, other film and pre-production elements, interviews, and transcripts from A Question of Color and Remembering Thelma.

A Question of Color was the first documentary to confront the attitudes that many African Americans have about their appearances. Sandler interviewed a number of African Americans who provided testimony of their experiences and attitudes regarding color. Through the experiences of their testimony, Sandler examined the effects of "color consciousness" upon the black community. The roots of the phenomenon are traced to the preferential treatment that mixed race children would receive during the era of slavery, the effects of which are still present today.

Remembering Thelma is a short and vigorous profile of Thelma Hill (1924-1977). Hill, fondly referred to as "Mother" by the dancers with whom she worked, was a dancer with, among others, the Alvin Ailey American Dance Theater and the New York Negro Ballet Company. She also had a long career as a dance teacher with such organizations as the Clark Center for the Performing Arts in New York City, the American Dance Festival at Connecticut College, the University of Cincinnati, and the Davis Center for the Performing Arts at City College. Remembering Thelma contains rare footage of Hill with the Alvin Ailey Dance Theater and the New York Negro Ballet.
