When deciding what to do with your walls, you need to think about all the materials first. Put them all together like a designer would. Put your countertops, flooring, cabinet, hardware, backsplash, and paint samples all together to make sure they all blend. Notice I didn’t say match. They don’t have to completely match to look great. But they should be similar styles…all modern, all contemporary, all traditional. The colors should look good together. Don’t have all one color or all bold colors. Ground things with some neutrals or wood tones. Don’t just use color to add variety, use texture. Think about what mood your colors will invoke. See my blog on being your own designer for what moods different colors will bring out.
