Abstract: According to examples, apparatuses, systems, and methods for simulating the color appearance of coatings on three-dimensional objects are described. Geometric data relating to a geometry of an object characterized by a curved surface is received. A substrate representation of a substrate color associated with the object is determined based on the geometric data. A coating representation of a coating applied to the object is determined based on the geometric data and a thin film model of the coating. An appearance of the coating applied to the object is simulated by displaying the coating representation superimposed on the substrate representation.

Abstract: The present invention provides systems and methods for color tuning optical modules and executing color calibration methods on artificial reality systems and devices. Embodiments can include a lens with a colored coating, a plurality of cameras, including a visible spectrum camera and an infrared camera, each positioned behind the lens, and a processor and memory. The colored coating includes a plurality of regions for selectively transmitting light. The processor and memory can be configured to receive light information indicative of environmental information for executing an operation on the device, identify wavelengths of light reflected by the color profile in front of each camera, determine a color calibration to amplify wavelengths of reflected light, update the environmental information based on the color calibration, and execute the operation on the device.
