What color is this?

I have 2 porcelain hens and a millie fleur pair they're all d'uccles and the chicks have this whitish color to their wing feathers so what is this color?

It’s just chick plumage. Chicks go through lots of molts and all of them have different patterns. It should look normal as an adult.
