1. A method of controlling color of light in a room having one or more tintable windows, the method comprising:
determining a tint state for at least one of the one or more tintable windows using at least a clear sky irradiance value predicted to occur at a future time during clear sky conditions;
calculating a current internal color rendering index (CRI) value in the room using an external CRI value and the tint state of the at least one of the tintable windows;
using the current internal CRI value to determine one or more new settings for artificial interior lighting in the room, wherein the one or more new settings are determined to obtain a desired color of light in the room; and
sending control signals over a communication network to adjust the artificial interior lighting to the one or more new settings.
