What makes a color stick
Brand colors persist for the same reason brand names persist: repetition plus distinctiveness. A color that appears consistently across every touchpoint — packaging, signage, digital, advertising, physical environments — becomes associated with the brand through sheer volume of exposure. The psychology of color memory is favorable to brand building: humans are better at recognizing colors than at describing them verbally. You know Tiffany Blue when you see it even if you can't name its exact hue angle. This recognition operates partly below conscious awareness, which is why brand color changes feel viscerally wrong to customers even when they can't articulate why. The color has become a Pavlovian signal for the brand's entire emotional register.
