The SNCC refers to the Student Nonviolent Coordinating Committee, which was the main organization to facilitate student involvement in the Civil Rights Movement in the 1960s. The image of Lelache and Orr’s shaking hands (and the pin the image evokes in Lelache’s mind) seems to mimic the Taoist symbol for
yin and yang, which also features contrasting light and dark colors. The principle of
yin and yang is that seemingly opposite forces don’t inhibit but
complement one another, which seems to be the idea reflected in the SNCC pin: that different races can complement one another rather than be divided.
