Blue. It's the color of the ocean, the sky and Ryan Gosling's eyes.
Unlike warmer colors such as red or yellow, which trigger strong emotions, blue has a calming effect and is generally associated with stability and depth.
Companies will often use the color blue to promote a sense of purity, which is why you frequently see blue on products like water filters and cleaning supplies. Blue is also a very attractive color to men, who often associate it with expertise and precision. This may be one of the reasons that blue has become a go-to color for corporate America (think IBM, Chase and Jet Blue).
Of course, blue can also represent feelings of sadness and depression, hence the phrase “feeling blue.”
Around the house, blue is a great color for bedrooms because it will help you relax as you go to sleep. In fact, blue is so calming it can even slow down your metabolism!
One room to avoid using too much blue in is your kitchen or dining room. Besides blueberries, there aren't any naturally occurring blue foods, so the color acts as an appetite suppressant and might leave you feeling full before you've had a chance to clean your plate!
