the pics i have found on the internet sucks at comparing the 2, do anyone have any better pics? is the gunmetal THAT much darker than the steel grey? or are they basically the same? it would really help if you had a pic of the two side by side, thanks.

Yes the gunmetal is significantly darker.

Check out www.jlbmotorsports.com for Rotas.
EDIT: More specifically, here's their page about colors etc http://www.jlbmotorsports.com/RotaCnMguide.html
