It has long been theorized that color can have an immense effect on human emotion. There are a variety of explanations for this occurrence. On some levels, this effect on emotions is argued to be universal; warm colors raise the spirits and cool colors assist in creating more calm emotions. Beyond this general explanation, some believe that particular color emotion effects are attributed to cultural condition and for that reason; some effects of color on emotion are subjective depending on the individual. Though not all aspects of the affect of color on emotions are agreed upon, in western culture there are a list of accepted color emotion associations. There are many emotions that have been proven to effect emotion; warm colors include red, orange, yellow and green. Red is a color that can evoke a great deal of emotion. It is noted that red can increase a sense of vitality, ambition and also the negative emotional effect of anger. Pink, a derivative of red, is a color that is most noted for its connection to emotion. Pink is known to increase feelings of love. Orange, unlike red, is only reported to have positive effects on human emotion. It is a color that acts as an anti-depressant, alleviating negative feelings such as low self-worth or high self-pity. Yellow is also a color that uplifts the emotions. Yellow can increase optimism and confidence.
Blue, green and purple/violent all belong to the category of cool colors that affect human emotions in a different way from that of warm colors. Blue is a color that has an extensive effect on emotion. Blue is a color commonly associated with the ocean and sky and can be considered in clear opposition of the excitable effects of red; it prompts emotions centered on peace. Some brighter shades of green can be considered more on the warm side, but for the most part it is a color that bridges the gap between the uplifting warm colors and the calming cool colors. It can make people feel calm, relaxed and experience an overall emotional comfort, which is due to its connection to nature. Purple and violet are also cool colors that can calm human emotions. In addition to relaxing people, it can create feelings of spirituality and creativity. Though black, gray and white are neither warm nor cool, they do have an effect on emotion. Black is known to be a color that can sometimes be depressing, often associated with death. White on the other hand, evokes emotions that make people feel open, free and pure. Gray is a color that has an unclear effect on emotions, but in some respects it is thought of as a depressing color, such of that on an overcast day with gray clouds.
