Abstract

A method may comprise: commanding, by a processor, a lighting system to generate a first desired effect in accordance with a first spectral weighting mode; determining, by the processor, a first optimized predetermined variable within a first predetermined domain to generate the desired effect based on the first spectral weighting mode; commanding, by the processor, the lighting system to transition from the first desired effect to a second desired effect, the second desired effect in accordance with a second spectral weighting mode; and determining by the processor, a second optimized predetermined variable within a second predetermined domain to generate the second desired effect based on the second spectral weighting mode, the first optimized predetermined variable being different from the second optimized predetermined variable.
