When light hits the surface of the duck skin, it is scattered and refracted in a way that makes it appear blue to the human eye. This is similar to how the sky appears blue due to the scattering of sunlight by the Earth's atmosphere. The blue color of the duck skin is temporary and will change as the light conditions or viewing angle change. **
