This hue is inspired by the bright yellow of classic prepared mustard, the condiment that’s as visually bold as it is tangy. The color comes from ground mustard seeds mixed with turmeric, which lends both its sunshine hue and earthy flavor undertones. First commercialized in the United States by George and Francis French in 1904, “yellow mustard” became the ballpark standard, its vivid color as recognizable as its sharp, vinegary bite. Today, that unmistakable shade is more than just a topping—it’s a cultural staple, splashed across hot dogs, sandwiches, and summertime cookouts.
