Orange is the complement of blue, so indigo ceramics, denim, navy bags and teal glass look rich against it. Black and white products also hold up well.
Peach (around #fdba74) is warm and gentle for beauty and home goods. Tangerine (around #f97316) is bold and good for sports and snacks. Burnt orange (around #c2410c) feels autumnal and premium.
Wood, leather and terracotta products can blend into an orange backdrop. For those, use a cooler background such as teal or blue, or lighten the orange to peach.
Pick any shade in the Change Background Color tool, or start from a color below. Marketplace main images usually need pure white, so use the white background tool for those.
