I've never understood the Avalanche rage either, very overrated color that isn't anything that special on the 2017's I saw unless they changed a lot of other aesthetics as well. In person the Iconic Silver is one of my favorite colors.
Had an AG GT350... loved that color. Ended up with LFG on the Gen3 as I had ever seen Iconic Silver in person. Loved IS after I saw it and would have changed if I could have. Still loving my LFG though!
AG is person is one of my favorites if you don't want CO. I have seen an Atlas blue and iconic silver in person as well, both look really good. I am with you, I don't dig the white. You will be happy with AG, its unique. Lots of other cars have iconic silver type colors, sticking with AG is my vote.
AG is cool. And I don't like gray.White is the most practical. Silver doesn't do it for me, I've never seen one that I liked. But it is practical and nearly as good as white at hiding dirt and blemishes. My second choice would be red. But that's an old man color. It may become stylish again, who knows. As far as being in style goes, it seems to me that gray is getting damn old. It's probably time for a new trend, so be careful if you care about looking like the twenty teens ...
