Why does a violent dress appear to be Violet in sunlight?

A dress that appears violet in sunlight likely contains pigments that interact with light in such a way that they reflect wavelengths corresponding to violet. In bright sunlight, the full spectrum of light is present, which can enhance the visibility of certain colors. The perceived color can also be influenced by the surrounding environment, lighting conditions, and the way our eyes perceive color. This phenomenon is a result of how light interacts with the materials and pigments in the dress.
