Best Exterior Blue Paint Colors for Home Siding

Navy, coastal blue, and slate blue exteriors. What looks best in PA neighborhoods. In our experience painting hundreds of homes across the Lehigh Valley, these are the color choices that consistently perform best.

What to Look for in Exterior Blue Paint

Not all exterior blue paints are created equal. Undertones are the hidden quality that makes some exterior blue colors look beautiful in your home while others read wrong despite looking similar on a chip. Always evaluate undertones before committing.

Top Exterior Blue Options We Recommend

After painting thousands of rooms across Easton, Bethlehem, Allentown, and the Lehigh Valley, these are the exterior blue colors our clients consistently love:

• Light exterior blue - Best for smaller rooms and north-facing rooms that need brightening
• Mid-tone exterior blue - The most versatile option, works in nearly any room
• Deep exterior blue - For dramatic accent walls, dining rooms, and rooms with strong natural light
• Greyed exterior blue - The sophisticated, muted version that reads as a neutral

How Lighting Affects Exterior Blue

Lighting changes exterior blue dramatically. In north-facing rooms, exterior blue can read significantly cooler and darker than you expect. In south-facing rooms with warm afternoon light, exterior blue may appear warmer and lighter. Always test large samples in your specific space.

Testing Paint Colors in Your Lehigh Valley Home

We recommend testing paint colors as large samples (12x12 inches minimum) directly on your walls, leaving them for 48 hours to evaluate at different times of day. Peel-and-stick sample cards from Benjamin Moore or Sherwin-Williams make this process easy and low-commitment.
