Here's Joey around 5 or 6 months, there's a little black, but the roots are silver, I guess they call that sooty.
This is Joey at 15 months, his head is very silver, but it will turn light beige soon.
This is Joey at 2 years or more, his head is golden beige, with his mustache area being a little darker.
This is 5 plus years his color has stablized, and his head is beige and gold.
