How to Choose Your Beach House Exterior Color Palette
Look at your fixed elements: roof, brick, stone, concrete, landscaping.
Test BIG samples in daylight (morning + afternoon)
Let your style lead the palette: cottage, modern, classic, serene, moody…
Pick the vibe first then the color: soft + serene, modern + crisp, moody + coastal.
Choose trim with intentional contrast: too close = flat, too stark = harsh.
Lighter exteriors hide salt, sand, and sun fade better (your future self will thank you.)
Keep siding soft and use deeper colors on doors, shutters, porch accents, and decor for personality.
Remember: your accent color sets the personality.
A great example of how soft siding + crisp white trim = instant coastal curb appeal.
