There are many shades of colors you could choose from ranging from black and white to brighter, colorful shades. It all depends on your taste and what you would like to have in your space. Make sure to add some waterfall pictures to those boring bare walls of yours. You can also get creative and take a picture of a waterfall the next time you go out for a vacation with your family. You could have a picture taken of your family against the background of the waterfall. Get it framed and then hang it in your living room wall by using photos on canvas. Wall art is all about creativity so there is no need to limit yourself.
