How you choose to paint or finish your baseboards is critical to the overall look of your home. There are some things to consider, such as the color of your floors, the color of your walls and also the style that you are trying to achieve in a particular room. So before deciding on how to finish your baseboards decide what it is you want the end picture to look like.
Paint all the baseboards in your home white, regardless of the color of the walls. Painting the baseboards white will help define the wall and allow the color on the wall to stand out. White baseboards will freshen up any room, even if the color on the wall is dark. White will also match with any type of flooring that you have down.
If you paint your wall a chocolate brown, consider painting the baseboards a lighter tone of the same brown, rather than leaving them a stark white. This look will be easier on the eyes, making the color of the baseboards blend in with the paint on the wall, yet still giving it enough of a contrast to be noticeable.
If your baseboards are a natural wood, or if you have other stained trim throughout your house, stain the baseboards to match. Staining the baseboards will compliment any color that you choose to put onto your walls. However, if you have hardwood floors the stain of the baseboards will need to match or compliment the color so that they do not clash with each other.
Paint your baseboards the same color as your walls. Choosing to do it this way will hide the baseboards and will blend them in with the wall.
