1. A lighting system comprising a luminaire that includes: a plurality of light channels that respectively produce different spectral distributions of light; a drive circuit coupled to the light channels and programmable to control relative intensities of light output from the light channels; and an interpreter module that processes a script to generate operating parameters for the drive circuit, wherein the script comprises a plurality of descriptors in a sequence that represents that a lighting scenario changes over time and wherein programming the drive circuit with the operating parameters results in the light channels producing the lighting scenario.
