I Trust Blue

WELCOME TO THE WORLD’s favorite color: Blue. Though popular across all genders, this color can also be perceived as cold, unemotional and unfriendly. Our association to blue is intrinsic to us, not necessarily because of it’s relation to the colors of oceans and skies, but how we, as a specie, defined these elements when we were wired as hunter-gatherers.

Blue is part of the triumvirate of primary colors that include yellow and red. Remember kindergarten? And so, it may be said that the color blue is among the first colors we got to see, use, and learn. A favorite of renowned painters, the color blue imbues trust and is said to be the color of clear communication. The qualities it is known for are intelligence, duty, efficiency, coolness, reflection, and calm.

The Blue Room. According to Designlike, you can use blue to cool a room with much sun and heat. Using a light shade of blue also makes a room look spacious. If used in the kitchen (or dishes), blue color is said to decrease appetite.

Described as an “Intellectual” color, blue can be beneficial—and is actually often used, in work stations. Blue is proved to be more powerful in elevating body temperature and heart rate and in reducing sleepiness, says Gilles Vandewalle of the Center for the Study of Sleep and of Biological Rhythms at the University of Montréal, citing that performance improves acutely after the onset of light exposure, both at night and during the day.

Electroencephalography or EEG—an electrophysiological monitoring method to record electrical activity of the brain, has shown that light exposure reduces alpha, theta, and low-frequency activity, which are correlates of sleepiness. It was revealed by Gilles Vandewalle that blue light proved superior to other wavelengths in enhancing responses in the left frontal and parietal cortices during a working memory task. Experimental subjects had quicker auditory reaction times and fewer lapses of attention under blue light than green, the study says. In further experiments using EEG, blue wavelengths suppressed sleep-associated delta brainwaves and boosted the alpha wavelengths, which are related to alertness, which drives to the point that one may be able to use short [blue] wavelengths as a sleepiness countermeasure.*
