Darker colour indicate better absorption of light.
Shiny surface is due to it reflect off the light.
When the object to totally dark it is because it absorb all the light and transform to heat.
You might want to proof it by placing black object and shiny object in the sun, wait few hour and see which object is hotter.
Materials that are good absorbers of light include black surfaces, such as black paper or fabric, as well as materials with dark or matte finishes. Pigments like carbon black or graphene can also absorb light effectively. Metals like gold and silver can also absorb light, particularly in the visible range.
Black bodies are good absorbers of heat because they absorb a wider range of wavelengths of light, including visible and infrared. Their dark color allows them to absorb more light energy, converting it into heat more efficiently than lighter-colored surfaces that reflect more light. This absorption helps black bodies retain heat and warm up quickly in response to radiation.
Materials that are good absorbers of radiation are also good emitters of radiation. This is known as Kirchhoff's law of thermal radiation. Good absorbers like black surfaces are also good emitters, while poor absorbers are poor emitters. This is why black objects heat up quickly in the sun and cool down quickly at night.
Materials that are dark, rough, and thick tend to be good absorbers of heat, such as black metal or asphalt. In terms of sound, soft and porous materials like foam, carpet, or curtains are good absorbers.
Dull black surfaces are considered good emitters or absorbers because they have a high emissivity, which means they can both absorb and emit radiation efficiently. The rough surface of a dull black object traps more light and heat than a smooth surface, allowing for efficient absorption and emission of energy.
Good absorbers of heat radiation are like basically materials which are dark in colour. Because for some reason they tend to absorb more radiation than light coloured materials.

It is about pigments. they are absorbers of light.
it's reflectors.....

Yes, Good absorber of heat are good emitters of heat. And in both the way rate is same. This is Kirchoff's Law.
yes
Dull black surfaces are considered good emitters or absorbers because they have a high emissivity, which means they can both absorb and emit radiation efficiently. The rough surface of a dull black object traps more light and heat than a smooth surface, allowing for efficient absorption and emission of energy.
Surfaces that are dark, rough, and opaque are good absorbers of infrared radiation. Materials like asphalt, concrete, and vegetation are examples of surfaces that absorb infrared radiation effectively.
