Danger

red is the color of power and danger in the natural world. Our earliest ancestors experienced the light and warmth of the sun, the burning heat of fire, and sometimes the glow of molten lava. Poisonous animals and plants are often red as well. We have learned to treat red things with caution, and we choose red to color our warning signs, such as “Stop,” “Danger,” “Poison,” and “High Voltage.”
