Because they absorb them better. If a surface were to absorb a certain radiation very well and not radiate it well, an apparatus could be made that violates the Second Law of Thermodynamics (creating a temperature difference where none existed previously). Therefore, it is not possible.
You might also say that the dark surface is "transparent in both directions" (in and out). This is for a specific radiation; on the other hand, it is possible to have surfaces that radiate and absorb electromagnetic waves of one frequency well, and not so well at other frequencies.

Do darker objects radiate heat better than lighter objects?
YES
Does heat radiate through glass?
Yes, heat can radiate through any kind of physical matter if it has been there long enough - heat can radiate through concrete, it just takes a while.
Objects that absorbs and radiate heat?
Styrofoam
What is a sentence for radiate?
Heat will radiate throughout the room when a wood stove is burning.
Which kind of surface can radiate heat quickly to the surroundings?
the surfaces with larger surface area radiate heat quickly as compared to those with lower surface area
Do darker objects radiate heat better than lighter objects?
YES
Why do people who wear dark clothing in the summettime put themselves at a greater risk of heatstroke?
Dark clothing will absorb sun and heat. This can cause an excess of heat to radiate onto and in the body and increase risk of heat stroke.
Do dark rocks absorb more heat than light rocks?
Dark rocks will absorb more radiant heat than light rocks, for the same reason that any dark object absorbs more heat than an equivalent light object. Light objects appear "light" to us because they reflect more light than objects which appear dark. Dark objects appear dark because they absorb more light and reflect less. However, dark objects will radiate more heat that light objects. Actually, dark rocks do NOT absorb more radiant heat than light rocks. Nor do they radiate more heat than light rocks. Dark rocks DO absorb more LIGHT than light rocks and they then radiate this light at heat. Light rocks reflect the light rather than absorb it and therefore do not radiate as much heat. If you put a light rock and a dark rock next to a HEAT source, the amount of heat absorbed will be related to the makeup of the material rather than to the color.

Why paint the oven shelf black?
Black absorbs heat instead of radiating it away so would heat up the oven quicker ;)

Does color affect heating by absorption of light?
yes it does if the material is dark it will be warm if it is light it will be colder Yes, darker colors generally absorb AND RADIATE more heat from radiated. Meaning that if there is plenty of radiated heat available for example from the sun, dark clors will absorb more. If it's dark and cold out and the surface is hot, a dark surface will also RADIATE more heat than a lighter colored surface. It's called "black-body radiaton."
Are there better heat sink properties in dark clouds or light clouds?
Dark clouds. This is because dark colors take in/absorb more heat and sunlight than lighter colors.
What does silver layer of an insulated bottle does this to radiate heat?
fddf
Names of everyday things which radiate heat?
microwave and oven
