Working with what stays
Choose the correct wall surface
The rustic stucco-like example, lap-sided ranch and painted-looking rowhouse have different textures and proportions. Use the example closest to your own surface before choosing the depth of clay color.
Keep the trim from adding another unrelated warm tone
Compare stone-colored or quiet light trim against the wall. If the existing shutters are dark green, preserve that version while testing the body before changing both together.
