Answer
HEllo again Neville.
Your Amazon sounds like a great bird!!!  
As for the grey in his feathers, I really don't know.  It's possible that he's getting ready to molt and the new feathers will come in the normal color.  I have never seen this before, but by all means, do NOT give him anything with artificial coloring as this could poison him.
Do, howver, keep up with the vitamin supplements once a month and be sure that he gets fresh fruits and vegetables every day.

God Bless.
