This can't be corrected with filters or other methods after the light is manufactured. What works is setting standards for light quality and testing that standards are met.
It is well documented that color balance of surrounding light can affect how a screen or picture looks to the human eye. Yet color photo printing filters were selected best by human eye looking at calibrated monitor showing how picture will look, compared to reference color picture that includes proper flesh tones and surrounding white area that calibrates the eye to white balance standard. This is how it was easiest done when I was printing color photos from color negatives.
