Would you paint your house foundation the same color as your deck?

You could or you could leave it the natural color it is. Once you paint it you'll have to upkeep it; in other words repainted it.

I would because it would blend in. It would stand out if you used anything else.

I stained the concrete of my house foundation to better match my plants, and I made it blend better. I haven't had to upkeep anything in 5 years, but that doesn't mean that eventually I won't have to. Now I wouldn't ever paint the concrete, because foundation concrete gets more water wear.

I would, but that's because I could get the foundation painted more consistently than I would be able to keep up the maintenance of camouflaging plants and trees. If I could keep up, I would go with foliage. Best wishes 😇

I think it really depends on the color, but in theory, I totally would.
