Nature is much better at adding color to walls than any coat of paint. Unfortunately I am not sure how I ended up with this image. If you happen to know where it's from, or who took it, please let me know. I'd be happy to give proper credits.
Assuming the background is a wall treatment, it's a lovely combination of rose, salmon, and softened berry colors. It could be a fresco; no details are provided at the source, but the surface color and its variations are are restful and refreshing.
