Companies around the world research the best colors for their logos. Google tested 40 shades of blue before deciding which blue to use in their logo. The psychology of color plays a role in most of these decisions, such as red signifies warmth, passion, and sales! Blue is calming and trustworthy, while green signifies health. Chanel, coined “the little black dress” and continues to use black in their logo symbolizing classic and sophisticated designs.
We see images via the visual cortex portion of the brain. However, the retinal ganglion cells are the first responder neurons, sending signals to the hypothalamus, part of our brain’s limbic system. The hypothalamus helps maintain balance with our body’s internal environment (hunger, thirst, temperature, and sleep). It also triggers secretion of hormones that affect our mood, emotions, and need for reward. Here lies the key to how different wavelengths of color affect our mood.
Blue/green wavelengths, such as in morning light stimulate the hormone cortisol, which stimulates us to awaken. Therefore, it is hard to go to sleep after working on the computer for hours, unless you wear blue blocking glasses, such as EyeYee. I discovered this secret after experiencing many sleepless nights and eye strain while writing my dissertation. Keep in mind, too much cortisol released in our body causes stress and anxiety. (Could that be the reason why people tend to be more anxious after hours of computer gaming? Don’t go there! LOL.) Whereas, soft oranges/yellows in sunsets encourage melatonin production and help keep our sleep cycles on schedule; that why I recommend using warm lights in the bedroom to encourage restful sleep.
One Tokyo railway line installed blue lights at the end of their platforms and claimed they had a 74% reduction in suicide at these platforms. However, Nicholas Ciccone, PhD found inconclusive evidence regarding the effects of blue light on impulsivity. Correlations can be a bit misleading, but they do sell headlines! Two of the world’s largest restaurant food chains rely on color science for their marketing. McDonald’s has maintained their golden arches and red accents, while Subway adds a pop of yellow and green. Volkswagen maintains their image as “the car of the people” while encourage trustworthiness with the blue background in their logo.
As a researcher in interpersonal communications, I would love to hear your feedback regarding your choice of colors for clothes and possible effects on conversation.
Best to you all,
