COLOR TEMPERATURE Refers to our sense of warm or cool colors. For example, red is warm in temperature because it refers to blood, fire, and the sun; blue is cold in temperature because of its reference to water, ice, and the sky. Each primary and secondary hue also has a cool or warm aspect; for example, red is cooled when blue is added, creating red-violet.
