Have you done any research on Shaker villages, especially with websites that show their buildings? We have actually stayed at Pleasant Hill, Kentucky in the old buildings. I haven’t been there in several years so I cannot remember any specific building painted yellow. I would contact them and any other Shaker museums and talk to the conservator, the grounds manager, the project manager or whatever they call their experts. I have always had good luck with Benjamin Moore paint historic colors and Williamsburg colors. You are looking for a yellow with brown in it, I imagine. Here in the States, I have all my old Early American Life magazines and a stash of the now discontinued Colonial Homes magazines. I often page through them for a color or an arrangement or an idea. I know people don’t use libraries any more, but they used to have shelves of books on historic houses. I love the idea of the Shaker yellow. I’ll be smiling all day!

Thank you for your response. I did email Shaker Village of Pleasant Hill and I received a response this morning. They are going to ask their Building and Maintenance Manager. I have also looked at Benjamin Moore Historic Paint and found a few that are similar to the yellow at Pleasant Hill. I plan to go to the store tomorrow to look at the swatches. That colour makes me smile too.
