I would paint it the same color as the siding.

Agree. Not something you want to feature or draw attention to, especially if visible as guests approach. If it’s only viewable to the homeowners, then I’d pick any color I want. If you’re a gardener, then maybe a color found in the garden.

Color of stones and roof might blend in.

For outside I would paint it similar color like your siding. On the inside, paint your favorite color! :)

If its viewable to people coming to visit,l then, I would want it painted the color of the siding. If it is in the back of the ho use, where mostly family gather, then, I would like it a pretty happy color of your choice.

I need to see the house from further back to see exactly what guests see when they come. If they do not see this why bring attention to it at all just paint the same as the siding and have it disappear..
