Tips for Choosing Coastal Blue Paint Colors
- Light Reflectance Value (LRV): Higher LRV values indicate a lighter color that reflects more light, while lower LRV values represent darker hues. Consider the amount of natural light in your space when choosing your shade.
- Peel and Stick Samples: The best way to test paint colors in your home is to use peel-and-stick samples or paint swatches on a pure white backdrop. Observe how the color changes throughout the day.
- Blue-Green vs. Pure Blue: Many coastal blue shades have green undertones, which can help warm up the space. If you prefer a cooler or more neutral feel, opt for colors with gray undertones.
By following these tips and considering your lighting conditions, you're sure to find the perfect coastal blue to bring a relaxing, beach-inspired feel into your home.
