This paper presents the calculated and experimental interference colors of liquid crystal (LC) films due to the optical retardation of two orthogonal electromagnetic components at different surface anchoring conditions and applied voltages. We simulate the deformation of LC director using finite element method and convert the calculated colors into sRGB parameters. A gold micro-structure is fabricated and used to control the optical retardation. Polarizing micrographs were collected and compared with the calculated colors.
