In short, because they "don't reflect'."
A matte surface isn't smooth; it has a surface that does not fully reflect light/radiation; the surface looks dull because there's little reflection.
A smooth surface will reflect because it's smooth (glass-like) and will reflect or bounce light away from its surface. The surface looks shiny because of the reflection.
The color of the surface matters because the darker the color, the more light/radiation is absorbed. Lighter colors reflect light; darker colors absorb light.

It is just that Matt black things are good absorbers (and emitters) of radiant energy. Black is a good absorber of radiant energy because unlike white it does not reflect light but absorbs it.

it radiates exactly the same amount of radiation as it absorbs.

What colors reflect radiant energy?
i think its black
What absorbs radiant energy?
Darker colours (ex. black, navy blue) absorb more radiant energy than light colours, like white. Also, it helps if the surface is dull (not shiny) and cold at the beginning, because cold things absorb more radiant energy.
If you know that a surface is a good absorber of energy what can you infer about its ability to radiate energy?
Yes. As for the reasons, one of them is that if this were not so, the Second Law of Thermodynamics would be violated, because two side-by-side objects, one black, one white, would develop a temperature difference.
Are blackbodies black?
No. The black is an ideal condition, but not necessary.
Which law governs the distribution of radiant energy over wavelength for a black body at fixed temperature?
wiens law
How can the knowledge that black absorbs radiant energy and white emits radiant energy be used in real life?
Because light is absorbed by black and is not by white.

Why drain pipes are always painted black?
black is a good absorber and hence a good emmiter of thermal energy. painting the surface black can increase the rate of this transfer of energy, and hence thedrain pipes are painted black:)

How is radiant energy different from energy of motion and stored energy?
Surprisingly there is little difference. radiant energy transfers watts through massless particles call photons. You could actually push a black sail with light if you had a light source bright enough. The only way to store radiant energy with only one conversion of energy is electrically into a battery; you could use a photovoltaic cell. Still, all forms of energy can be converted to another form.
Which color is the best absorber of heat?
Black is.
How does the color of something affect radiant energy?
The color will determine if it can reflect light energy being a perfect black body that does not reflect and a perfect white body
Why utensils are painted black?
The utensils are painted black because black is a good absorber of heat
What materials reflect radiant energy?
The heating of a solid body, which absorbs radiant energy, was studied. With sufficient radiantenergy flow, the surface of the body can achieve such a high temperature that the physiochemical conversions of the material are unavoidable. Emphasis was placed upon the one-dimensional problem of the evaporation of the solid body, heated from the incident radiant energy. It is assumed that the flow of radiant energy is absorbed on the surface of the body and is equivalent to the thermal flow q on the boundary whose value depends on time t and on the surface temperature. There are two cases of surface evaporation examined: body evaporation and evaporation into the medium filled far from the body.
