In India, the colorful milk packets found in supermarkets and local dairy shops serve a practical purpose beyond aesthetics. Each color corresponds to the fat content and type of milk, creating a simple and effective color-coding system. Blue packets typically represent toned milk, containing about 3% fat, while green packets indicate standardized milk with roughly 4.5% fat. Orange packets are for full cream milk, which has around 6% fat. Some brands even use magenta packets for double-toned milk, containing approximately 1.5% fat. This system allows consumers to quickly identify their preferred milk type without needing to read labels, especially in busy shopping environments. Despite common misconceptions, the color of the packet does not reflect the quality of the milk; it merely indicates its fat content. As families have adopted this color-coding over generations, it has become an integral part of shopping behavior in India, showcasing how design can influence everyday habits.
