Color relativity is how colors appear when they are with other colors. How colors are perceived by us may be very different than how they are in reality, and are Dependant on a number of factors. The intensity of light and shadow, the warmness or coolness of the ambient light, and the color of other objects nearby can all affect how a color is perceived. In art and design, color usage can create striking optical illusions which change the perception of color value, tone, and hue. Do you know someone who has hazel eyes that appear to change color depending on what they wear? Or how about that car that seems to change color depending on the surroundings? These are real life examples of color relativity.
