Thank you for your question. Classic bead board porch ceiling is light blue so you might like a light blue-gray such as Benjamin Moore's #1563 "Quiet Moments", #1626 "Gentle Gray", #1633 "Brittany Blue" or #1639 "Windy Sky". Bead board is usually painted in a satin finish.
I like the walled in design of this bench & upper storage. The walls support the uppers but also tend to divide the space per function or passage. I like it.
