The fresh duck skin turns blue due to a natural phenomenon called refraction of light. 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. **

When a fresh tattoo is healing, the skin goes through a process of regeneration and renewal. As the tattooed area heals, the top layer of skin may start to peel off, similar to a sunburn.

It is important to resist the urge to pick or peel the skin off, as this can interfere with the healing and potentially damage the tattoo. **
