Yellow
Our eyes see yellow 1st, so sales stickers grab our attention. Good design – use yellow for kids/leisure goods. Otherwise as a highlight only, & not on pricey items (especially for men, as they regard it as cheap). Yellow & black is highest contrast colour combination, good for warning signs to be read at speed, distance or night. Bright yellow was reserved for emperors in ancient China
