1. An article of manufacture including a tangible, non-transitory computer-readable storage medium having instructions stored thereon that, in response to execution by a processor, cause the processor to perform operations comprising:
command, by the processor, a lighting system to generate a desired melanopic effect in accordance with a spectral weighting mode;
determine, by the processor, the spectral weighting mode based on an algorithm that compares a part of a spectrum for an amount of melanopic lumen to a melanopic sensitivity curve to generate a result comprising a melanopic ratio; and
in response to the result comprising the melanopic ratio, determine, by the processor, a visual brightness by multiplying the melanopic ratio with an amount of color temperature associated with the spectral weighting mode thereby inducing a desired melanopic effect,
wherein the color temperature comprises a white color temperature, and
wherein the white color temperature for the desired melanopic effect comprises a melanopic mode of an amount that is produced by the spectral weighting mode comprising a cyan color set at a percentage with a color temperature mixture comprising at least a set of a first color temperature, a second color temperature, and a third color temperature.
