Help with color of silkie chick

[BantamFan4Life]

Wow! I've been trying to find answers about the future color of my silkie babies with no luck. When I got them at the feed store I got one yellow, one black and one gray. Now, at 4 weeks, the yellow is getting a lot of brown, the black is getting a gray head, and the gray is turning black! Anyone know what they will eventually look like? Sweet little things...

They're so cute!

I may be wrong.... !
They are cute...!
