Abstract
This article presents a methodology and the results of an experiment studying the perception of oil paintings under electrical lighting with varying correlated colour temperature (CCT). The experiment involved six paintings, differing in theme, colour palette, and painting style, with participation from 72 to 93 individuals per painting over a period of 10 months. A unique feature of the experiment was that each participant could independently select the CCT they deemed most suitable for illuminating each painting. For this purpose, a remotely controlled light fixture capable of CCT (Tcp) adjustment and a tablet with a Tcp control program were used. A large dataset was collected and statistically processed. The experiment revealed that despite significant differences in the paintings’ themes, styles, and colour palette, the majority of participants preferred lighting with a CCT close to 4600 K.
