We're working on the wall. The green looks promising.The colors used to create wood undertones are Benjamin Moore #1104 "Desert Beach" and #1117 "Guest House." The green is #SW6423 "Ryegrass." We've used oil-based enamels.
The green is thinned down 50/50 with paint thinner to create a light streaked/stained look. It may just work.
We are planning to replace the five rows of currently painted boards above the green to raw tongue-and-groove. Only after wielding the paint brush did we realize that it would look better to have the color end at the height of the built-in cupboards.
