Plan around the elements that are hardest to change. Unless you're doing a complete renovation, surfaces such as roof shingles or tiles, stonework, pathways and driveways will remain in place. Take these into consideration as you select exterior colors. Look for undertones between them that might inform your palette. Are they warm (beige, khaki, brown and rust) or cool (gray, blue and black)? Consider paint colors that will tie these fixed elements together in a harmonious way.
