Burnt Sienna, Yellow Orange, Olive Green and Violet Blue
Autumn at a market stall, with Yellow Orange like a pumpkin, Burnt Sienna like terracotta, Olive Green like a dried bay leaf and Violet Blue as the evening sky behind it all. Give the two oranges the lead and let the darker pair frame them. It translates well to a fall fashion capsule, craft beer labels or homeware ceramics; Violet Blue against Yellow Orange is fine for headlines but a little weak for small print.
