Benefits of Painting Wall with Bright Colors

Brightly colored walls save electricity in both direct and indirect ways. Since bright colors reflect light well, which means fewer light fixtures are needed, which saves money right away.

Indirect savings are obtained when the room is actively cooled. The majority of the light generated in a light fixture is converted to heat. This is especially true for incandescent lamps, which convert only 2 to 3% of incoming energy into visible light and dissipate the rest as heat.

Therefore, by lowering the energy required to generate adequate light, the electrical load on the cooling system can be reduced.
