Coloration 

When activating the Chromium, have you found it to take on a "reddish" color and then re-oxidize back to it's normal silverish/blackish coloration when exposed to air?

What chemical solution/process are you using for activating chromium, and why are you activating a chromium surface? I remember getting a dark color when stripping chromium from nickel, but I never tried to activate the chrome.
