The open issue of color management in circadian interior design between the practice of lighting and color design

In the last 20 years, research has been developed in the field of chronobiology and physiology to demonstrate the relationship between the health of the human organism and the light radiation that enters our eyes. These are known as the Non-Image Forming (NIF) effects of light. Nowadays, it has been scientifically shown that light radiation's parameters that affect our physiology are the quantity, the spectrum, and the time of exposure. These fundamental parameters impact our living in interiors, illuminated by artificial light, with scarce or no natural lighting. Until a few years ago, in the design field, there was a lot of skepticism about these aspects that the 2017 Nobel Prizes in Medicine genetically demonstrated. Today there is a growing interest developed in the lighting design sector, which, however, sees the need to deal with a holistic interior design vision. In this article, a review of current knowledge is proposed to favor the relationship between lighting and color design
