Contrast between cedar shake and vinyl siding colors prevents the exterior from looking flat or washed out. Without enough contrast—around thirty to forty percent body-to-trim difference—the house can blend into its surroundings, especially in cloudy climates. Contrasting colors highlight architectural details, add depth, and enhance curb appeal. Choosing a saturated teal or vine green body with lighter cream trim against beige vinyl helps maintain visual interest and an intentional design.
