It has been said time and time again that PAINTING is the quickest and most affordable way to update a space.
Honestly in my opinion I feel that there is no need to spend a ton if money on designer name brand paints unless you are going for a particular finish that can only be achieved with them. If you are just going for a color change Walmart paints are inexpensive and carry a warranty. Think about it, you’re just doing an interior paint job.
Try your potential color out in the space. Paint chips and samples are available through many companies. Lighting differs in all areas. This will allow you to view what the color will actually look like in the space before committing.
