Because the colour black is a good emitter of heat and therefore emits the heat away from the fridge since you would want the fridge to be cold.
Refrigerator bodies are commonly painted white because white reflects light and heat, helping to keep the interior cool. In contrast, black absorbs heat, which could cause the refrigerator to consume more energy to maintain the desired temperature. Additionally, white surfaces are easier to clean and maintain than black surfaces.
The cooling fins are painted black to improve heat absorption, as black color absorbs heat more efficiently than other colors. The rough surface increases surface area, which helps in dissipating heat more effectively, making the cooling process more efficient.
The cooling fins of a refrigerator are painted black to improve heat transfer efficiency. Black color absorbs more heat than lighter colors, helping the fins dissipate heat more effectively. This process enhances the overall cooling performance of the refrigerator.
Simply put a refrigerator works by moving heat from inside the fridge to outside the fridge. The grille at the back of a fridge is the place, where, just as with a car's radiator the unwanted heat is released. And black happens to be the color that is the best when it comes to releasing (and absorbing) energy.
A fridge cools things by removing heat energy from the inside of the fridge. This makes it cold inside the fridge. The heat energy that is removed ends up at the back of the fridge. The back of the fridge is often painted black because that makes it a good emitter of heat energy. The fridge may also have a metal cooling grille, also painted black, to help it loose heat to the air. The radiators in our house could be black and it would help them to emit heat into our rooms. In practice people do not want black radiators so they are generally white. the shape of a radiator is designed to give up its heat to air rising up through it.

To emit heat

The cooling fins of a refrigerator are painted black to improve heat transfer efficiency. Black color absorbs more heat than lighter colors, helping the fins dissipate heat more effectively. This process enhances the overall cooling performance of the refrigerator.
It's because of radiation that as you know black body is an ideal radiation body for good radiation and so good heat transfer.
That depends on whether or not you want a spray-painted refrigerator.
The underside of cooking pots and pans isn't always painted black. Only some brands are actually of black color on the bottom.

The utensils are painted black because black is a good absorber of heat
Emissivity of the black body is 1. And this is probably the reason that the condenser of refrigerator is painted black to loose heat efficiently by radiation ,though there are other modes of heat transfer like conduction and convection which is not affected by colour of the body
Black As He's Painted was created in 1974.
