I need to make an entire tier metallic silver.  I have an airbrush system and bought Americolor's silver airbrush.  No matter what base color I use (white or shades of gray) Americolor always looks greenish.  Does anyone have a different airbrush color or advice on how I can get a true metallic silver tier?

I have used the silver dust mixed with vodka to get the silver color.  REcently I did the same with a copper dust and vodka for a cake I entered in the fair and it came out awsome.
