help with paint colors / years

Im trying to figure out what other years have my 2001 galaxy silver color (for my fender replacement ordeal).
I am thinking silvermist was 97-00 and then switched to galaxy silver 01-03. Maybe the transition was 00. Maybe they overlap a few years?
I need to know because junk yards online aren't specific and all I generally find out is the year and that is "silver".
I thought there was a website that listed all this stuff.

Thanks.
(yes I searched)

thats a surprise the junkyards dont have the specific color. They usaully do at least where I live. Im pretty sure blackarrow will chime in with a link, he's pretty good at finding stuff.

I have both dealer brochures.....
2000 was Silver Mist
2001 was Galaxy Silver

Much thanks. Thats what I was looking for.
