How old are baby seals when they lose their color?

Seals are born with a white coat called lanugo, which camouflages them in the snow and ice. It helps seal pups hide from predators. The white coat is typically shed after 2-3 weeks, although the length of time can vary depending on the species and the specific pup. After they shed the white coat, seal pups usually have a gray or black coat similar to their adult coloration.
