+A Common LUT Format (CLF) file can include a series of color operators that transform color values between different color spaces. CLFs can be created with OpenColorIO and integrated into your application to manage color workflows.
+
+Currently, this parser does not implement all operators specified in the standard. If you need additional operators, feel free to open an issue or submit a pull request.
