Our house has been a dark blue with white trim for over a decade. We built an expansion in our back yard, and painted it a fairly saturated purple. It's not visible from the street (except one very narrow angle).

However, we received hate mail from neighbors who complained that the view from their 2nd story window into our back yard was spoiled, and that we should respect that we lived in society not in some hippy commune.

Other neighbors regularly bring their visitors to stand at the one tiny piece of the sidewalk where they can look down our driveway to see the purple, and point and shake their heads and grouse about it.

It's really kind of amazing how much hostility the color has generated. We used to be invited to neighborhood gatherings and cocktail parties and such. Now, because we callously refuse to repaint the extension and main house some sedate dull color, people literally won't speak to us.

This isn't an HOA neighborhood; it's an artsy-boho community known for creative types and public murals.

TL;DR people suck, colors are cool.
