Cover the bottom third of a wall with one color and the top third with a complementary color to create the wainscoting effect, even in the absence of the molding.
Paint three of the room’s walls one color and the final wall three shades darker than the primary color to create a focal wall in each of the rooms that run together.
Use a combination of paint finishes to better accentuate your rooms’ architectural features. Create a corduroy or velvet effect by painting one wall in a satin finish and the adjoining one in a semi-gloss.
