What are the psychological and physiological effects of different color families?

Different color families evoke distinct psychological and physiological responses. Hot colors, like red, orange, and yellow, are stimulating and can increase blood pressure and make people feel more energetic. Cool colors, such as blue, green, and violet, have a calming effect, can lower the metabolism, and may be used to create a sense of peace. Each color within these families has its own specific associations and effects. For example, red symbolizes power, yellow denotes optimism, blue signifies peace, and green represents growth.
