One Jim Crow law applied to all restaurants. It ordered everyone licensed to conduct a restaurant, to serve either white people exclusively or colored people exclusively. They were not allowed to sell to the two races within the same room. They also weren't allowed serve the two races anywhere under the same license.
Another Jim Crow Law prohibited certain marriages. The certain marriages were ones between a person of color and a white person. On the off chance a white person and a colored person did manage to get married, it would be considered void. This law was created to prevent white people from mixing with colored people. This is an example of how white people back then thought colored purple were not worthy enough to marry them.
