Add personality to a cedar shake house by incorporating a playful patchwork accent in small areas like the entry alcove. Use a mix of three greens and aqua tiles to create a whimsical yet controlled look that doesn't overwhelm the facade. Complement this with a joyful-colored door, like tomato red, to create a clear focal point. Keeping the main body and trim colors cohesive ensures the personality shines without sacrificing curb appeal or harmony.
