Making Red and Blue - Wht/silver metal

I have a logo and some text objects in motion3.

The logo is red/wht/blue the white is the background. I keyed the white out ( could figure out how to feather or soften the edges) and it look pretty good.

Now i need to make it look white or silver. I am cool with the white if i could get the blue&red to turn white.

Q.

How do i get the logo to turn white?

How can i make it appear to be tin or metal of some sort? (maybe even a reflection of some sort)

How do i feather/soften the edges?
