As Toronto heads into its first heat wave of the summer we are all thinking of ways to stay cool.
When looking at art, particularly larger scale mostly monochromatic art, viewers often dismiss the simplicity of the work and regard the large expanses of colour as meaningless. Think of the work of Rothko or Newman and the often uttered comment that “I could do that at home”. But what are we missing? When we take the time to look at Rothko’s or Newman’s larger bodies of work, and we consider the fact that colour fields and colour combinations affect us psychologically and physiologically, a more nuanced interpretation of the works can emerge.
The role of colour is often thought of in psychological terms meaning colour is interpreted symbolically through learning. For example, green is considered lucky for some cultures while in others it signifies royalty . Red signals attention and alarm or excitement. While psychological interpretation varies from culture to culture, actual physiological responses occur and may tend to be more universal in humans – though there is still considerable variability. How do we begin to examine the relationship between colour and physiological response? In physiological terms the eye transmits electrical impulses to the hypothalamus in the brain which in turn governs our hormones and our endocrine system. More specifically, the hypothalamus governs:
- water regulation
- sleeping and behavioural patterns
- sexual and reproductive functions
- body temperature
Think about the powerful role that colour plays in non-human animals, particularly in relation to mating rituals and the signalling of reproductive readiness. We humans, animals all of us, are also affected by colour. Have you ever wondered about the effect that colour might have on your physiology? Can blue really cool?
In California, bubble gum pink is used to calm children at a detention centre. In neonatal wards blue light is used as a treatment for premature babies born with jaundice. Color can change the perceived taste of food. Color affects blood pressure, pulses and respiration rates and brain activity and biorhythms.
Blue is the world’s favourite colour, so a work of art with a preponderance of blue has a better chance of being liked that one of yellow. Green is a close second. The blues and greens of water and vegetation begin to explain some of the popularity of landscape paintings. Research indicates that when people feel hot they prefer looking at blues and greens. Additional research on the physiology of colour effects indicates that blue helps people heal by soothing them – a greater portion of the energy directed towards day to day activities can be re-directed towards healing when a person is calm. Finally, “Through associations with the sky, the ocean and water, most people associate blue with openness, peace and tranquility,” says Zhu, who conducted the research with UBC PhD candidate Ravi Mehta. “The benign cues make people feel safe about being creative and exploratory. Not surprisingly it is people’s favourite colour.”
It’s a heat wave Toronto – so stay calm while enjoying the benefits of blue!
