Some subtstances are better than other at absoring radiation.
Dark,matt surfaces are good at emtting and aborsbing radiation. This show why solar panles are black because the solar panel can absorber heat quicker and better.
However on the other hand,
white light, shiny surfaces are poor at absoring and emtting heat. Despite this they are very goood reflectors which is good for reflecting heat. This is why a lot of thermos flask ask coated with a shiny white layer to reflect heat and keep your drink at the same temp.
