Use two to three exterior paint colors on cedar shake siding for a cohesive look. One saturated color like warm teal or green on the cedar shake, cream trim that coordinates with vinyl siding, and an accent color on the door create balance. This limited palette enhances curb appeal while maintaining simplicity and cohesion. Avoid multiple bold colors across large areas; instead, reserve playful patchwork patterns for small spaces like entry alcoves to add personality without overwhelming.
