Abstract: Properties of light impact both psychological and physiological aspects. In this context, the effects of light's correlated colour temperature (CCT) appear less studied than the effects of illuminance, although CCT is known to impact circadian rhythms responsible to maintain day and night cycles. Recently, Human-centric lighting (HCL) proposed to endow electric lighting with daylight dynamic characteristics with recognized benefits on physiological rhythms, particularly in reducing blue light exposure at night. Current lack of studies on the psychological effects of CCT prevents from reaching conclusions regarding the psychological aspects of HCL. The present user experiment aims to shed light on the relationship between HCL and personality, acceptance of an automated system to maximise daylight provision and visual comfort perception of occupants in two different buildings and within two types of offices. In this case, participants selected the HCL paradigm with dynamic CCT more often than a standard fixed CCT design, especially in individual offices. Despite being more frequently set and used to diffuse an appropriate light colour, dynamic CCT was assessed to deliver a heterogeneous light and decreased the overall visual comfort of occupants. Still, dynamic CCT was found to increase the acceptance of the automated system while mediating the relationship between personality and acceptance.
