We're building and are ready to paint. I was thinking BM flowering herbs downstairs and BM french olive for the upstairs, the colors would meet at the bottom of the stairs. I would like to decorate with BM sycamore tree green, yellow and terra-cotta - orange or something a bit brighter.Would this work? Now I saw this photo and am thinking maybe I should use this color instead, what gray would go with the shaker beige? Thanks for your help!
