Here’s a vital tip - I highly recommend that you avoid making your TV wide screen & entertainment centre the focal point or it will make your room look like a temple of worship to those items. Unless, of course, it’s a specific purpose built home theatre room.
Here are some guideline pointers – decide which you feel most comfortable following. If you’re just starting out, you may want to work with just one paint color on the walls throughout your home. You can always build on that later. Better to take it gradually, than to feel that you’ve overstepped the mark & don’t like it, can’t live with it, & have to redo it.
Ideally, colors are best flowing through your home – tones of the same or similar or complementary shades work best. Or graduations in varying intensities of the same color palette throughout your home also work well.
