Why Are Most Laundry Detergents Blue? The Surprising Science Behind the Colour

Have you ever looked at a bottle of blue laundry detergent and assumed the colour meant it was more powerful? It’s a common belief, but the truth is far more interesting. The blue shade found in many detergents has little to do with removing stains or making clothes cleaner. Instead, it is linked to colour science, optical effects and even consumer psychology. While the ingredients inside the detergent handle the actual cleaning, the blue colour helps create the impression of brighter, fresher-looking clothes.
