A warmer-hued gray helps a larger, rambling home, like this one, nestle into its surroundings. It can make the home appear less massive in scale and gentler on the landscape.
On the other hand, a cool, almost white gray gives a home's structure a real presence, especially when contrasted with the blues of the sky and water.
In its original configuration, the shingle-style house was covered in wood shingles that took on a lovely gray patina as they aged. Now, whether with wood or a fiber-cement material, the color gray suits this classic American home style.
A wonderful feature of the color gray is how with just the smallest amount of tint, the color can be transformed. You can take gray to a whole new place with just a hint of green or some other color.

This can be quite inviting, especially when teamed up with more colorful window frames and trim, as well as a roof that's allowed to weather to a natural gray.
