Cooling Costs

• The right color of paint can sharply lower cooling costs. Light colors, such as cream and beige, reflect summer sunlight. This helps keep homes cool and reduces air conditioning costs. If you live in a warm, southern climate and you're tired of hearing your air conditioner click on, paint the exterior of your home with a light color.
  
  

Heating Costs

• Just as light colors of paint reflect sunlight, dark colors absorb it. If your home is in a cold, northern climate, consider painting your home with a dark color, such as dark blue, green or brown. This will keep your home warmer and reduce heating costs.
  
  

Decks and Patio Furniture

• Because exterior surfaces painted with dark colors of paint absorb heat, they tend to get hot. If you paint a deck or patio furniture with a dark color, expect an unpleasant experience when you touch them with bare skin. Keep your deck and exterior furniture cool to the touch by finishing them with a light shade of paint.
  
  

Dangers

• Sometimes the wrong paint can lead to disastrous consequences. Since dark colors absorb heat, they aren't appropriate for exterior propane tanks. A dark color of paint may cause these tanks to overheat and explode. Many states have codes in place to regulate the colors for these tanks. Check with your local government before you settle on a color for one of these items.
