dark object absorb more light than light colors
When light hits a dark, heavy object, the object absorbs more light energy due to its dark color, which raises its temperature. The heavy nature of the object allows it to retain the absorbed heat for a longer time compared to lighter objects. This can result in the object becoming warmer compared to lighter-colored objects exposed to the same amount of light.

When light hits a colored object, the object absorbs certain wavelengths of light while reflecting others. The reflected light is what gives the object its perceived color. For example, a red object absorbs most wavelengths of light except for those in the red spectrum, which are reflected and detected by our eyes.
Dark colors absorb more light because they contain pigments that are better at absorbing light energy. When light hits a dark-colored object, the pigments in the object absorb the light rays instead of reflecting them, making the object appear darker.
Dark is not a color itself, but rather a description of the absence of light or the relative lack of brightness in a color or object. For example, "dark blue" is a shade of the color blue that has a lower light intensity.
When you put an object in front of light, the object can either absorb, reflect, or transmit the light. If the object absorbs the light, it appears dark. If it reflects the light, it appears illuminated. If the object transmits the light, it may appear transparent or colored.
Dark-colored surfaces absorb more heat than light-colored surfaces because they absorb a wider spectrum of light wavelengths. Light-colored surfaces reflect more light and heat, while dark-colored surfaces retain and absorb more heat.
No change will occur because shadow is a dark outline of an object, irrespective of the colour of the object or the colour of the light.
Black will be the color of a yellow object in a dark room while white light falls on it.
Green will be the color of a yellow object in a dark room while red light falls on it.
