This hue is inspired by the bright yellow of wet floor signs, a color chosen for maximum visibility and safety. Since yellow occupies the peak of human visual sensitivity, it can quickly draw attention and provide strong contrast against most flooring. Combined with bold black lettering or icons, the shade ensures warnings remain legible even from a distance or in low light. Since their adoption in the late 20th century, yellow wet floor signs have become a universal signal of caution—instantly recognizable in supermarkets, airports, schools, and workplaces worldwide.
