Every color has emotional impact attached to it. Blue has a reputation for instilling calmness and peace of mind in people, which stems from a blue sky indicating a lack of storms; this is why most social media websites have a primarily blue color scheme. The color orange is proven to help stimulate brain activity, and suggests enthusiasm and energy. Black is seen as an aggressive color; this association is likely related to fiction’s common practice of making “evil” characters themed around black. Like blue, green can have a calming effect and can reduce anxiety. Green also is the color that puts the least strain on one’s eyes.
