When it comes to saving money on your electric bill, your exterior paint color can affect the temperature of your house and how much power you may use for your Heater or Air Conditioner. 

You might even tend to just turn off the lights when you are not using them, wash less clothes, or turn off the air conditioner/heater, etc., but there is also another thing that can also affect how much electricity you use.

Selecting the Right Exterior Paint CAN Affect Temperature

I’m not talking about a color selection for your phone or room, I’m talking about the exterior paint on your home. 

Whenever it comes to summer time, the sun will absorb the color black, that is why if you were to wear a black shirt on a hot summer day, you will get sunburnt easier than someone who had a plain white shirt.

It is important to select the right color for your house because your exterior paint can affect temperature of your house depending where you live.

Why does Sunlight absorb Dark Colors?

The reason sunlight absorbs dark colors because they absorb more wavelengths of the visible spectrum.

The visible spectrum are the colors that you see everyday such as the blue sky and a white car.

The spectrum that is not visible to the human eye include microwaves and radio waves which are used to communicate on the phone.

Have a Light Color

Having a dark color for your home such as a dark brown, or a light black can cause your home to heat up in the inside more. It is stated that dark colors can absorb about 80% of the sun’s radiant energy which would then be transferred into the home, causing you to spend more money on your electric bill.


The same thing can be applied to a white color as well. During winter times, it is best to have a dark colored exterior paint applied to your home because the sun will absorb that dark color and essentially heat up the temperature your home a little more, which can save you money on your electric bill as well in the winter.


It would be good to go with a lighter color paint for the exterior of your home because it’s usually hot all year round in The Woodlands, Magnolia, and Houston Texas Area.

In the Texas heat it can get very hot, and if you do not pick a color with your brain, you will then have to pick the right color with your pockets.
