Lighting's brightness and uniformity matter
Pridmore makes recommendations for lighting paintings. He suggests that “Major factors to be considered when designing lighting for paintings include colour discrimination, colour diversity, clarity and the balance of cool-warm (bluish-yellowish) lighting. . . . High correlated colour temperature . . . appear bluish. . . . low correlated colour temperature illuminants . . . appear yellowish. . . .
Light intensity affects mood and alertness
Research Xu and Labroo published in 2014 was discussed in a 2017 issue of KelloggInsight, bringing their study findings to the attention of a broad audience of management professionals. As the article in KelloggInsight states, Xu and Labroo found that “bright light can make us a little hot under the collar.
Researchers have learned a lot about how the colors on surfaces and in light affect what we think
Glimcher and Tymula studied the effects of outdoor light intensity on risk taking behavior over a two-year period. They “found that increased luminance leads to less risk taking. . . . the effects are . . . consistent, significant.” Some useful definitions: “Risk attitudes refer to people’s willingness to take known risks. . . . ‘luminance’ is a measurement of the amount of light that falls on the surface of the earth.
Change color, change complexity, change response
Cheng, Ju, Sun, and Lin investigated what LED light levels are preferred by older viewers. They report on their research with people 55 – 65 years old: “In this study, experiments were conducted under LED lighting with . . . three different illuminance levels (30lux; 100lux; 1000lux). . . . they [study participants] prefer higher illuminance, which makes them find the lighting environment more comfortable, brighter, and better for reading.”
