How do colors affect our moods?

Artists believed that colors can affect mood and emotions a long time ago. Since the 20th century, designers have started to use color as a tool to make their clients excited, happy, or relaxed. In fact, little psychological research has been conducted to define the impact of colors on humans. Nevertheless, color psychology is an integral part of present-day art and design. Most of it is a make-believe psychology, but it does not prevent people from following the implications colors can bear.
Though the perception of color is subjective, many colors have universal meaning. Red, orange, and yellow (colors from the red spectrum) are known to evoke anger and hostility. Surprisingly, these colors are also claimed to bring warmth and comfort. On the opposite side of the spectrum, we have blue, purple, and green known as calm colors. They are often associated with sadness and melancholy. However, these colors are usually mixed. The effect of every particular color depends on its shade and intensity.
Colors evoke different reactions in people. Black, for example, is often perceived strong and powerful but also gloomy and depressing. White is the color of purity and innocence. We positively estimate white and fair clothes but the room painted in white looks cold, isolated, and almost hostile. While black and dark blue are considered masculine colors, white and pink look very feminine. The latter is associated with youth and romance, and some admirers of black may consider it childish.
