The color that absorbs all other colors is black. When all colors of light are absorbed, no light is reflected back, making the object appear black. In contrast, white is the color that reflects all colors of light and absorbs none. When white light shines on an object, the object reflects back all colors, making it appear white.
It’s worth noting that when we see colors, we are actually seeing the colors that are reflected by an object. For example, when we see a red apple, it’s because the apple is reflecting red light and absorbing all other colors. When we see a blue shirt, it’s because the shirt is reflecting blue light and absorbing all other colors.
