Which of red, orange, yellow, green, blue and purple absorbs the most heat?

Natural light is composite light, including red, orange, yellow, green, blue and purple. The greater the frequency of light waves, the greater their heat. So from red light to purple light, its thermal effect gradually weakens. For colored objects, the color of an object is the color of the light it reflects. For example, a red object reflects red light and absorbs light of other colors besides red light. White reflects all colors of light, and black absorbs all colors of light, so red is red.
