Before introducing the black color, I would like to say that there is no such color in the first place. Because black is not a color. On the contrary, it is colorless. So this color does not exist in nature. As the eye is misleading for the color that absorbs the light, we see it as black as the color. Black represents power, passion and maturity in most cultures. It is said that this color reflects positive effects on the persons according to some psychologists, while some talk about the negative effects of the opposite. In short, we can call it a controversial color. But when you look out on the street, you will see a lot of black over most of us. Black color, which is effective in people's psychology, means darkness on the one hand and lightness on the other. Crime, evil, difficult situations are always called darkness. But it is related to black color in patience, loyalty, endurance, wisdom or confidence. It also comes with meanings like pain and sorrow. Black color is usually preferred by highly-confident individuals, as long as we see the effect of black color on our lives. This color, preferred by determined people, ensures success in business life.
