Colors – how to change (FREE vs PRO)

Hallo there, can I change color in FREE version: Header black - to for example Grey? Hover color (right now red) - to Green? Promotional Button (red) - to Green? Footer (dark) - to Grey? Footer menu (black) - to different black? Im about to buy PRO - is it possible to change it there? I already somehow prepare webpage in FREE version. After getting PRO, how can I avoid to do it all over again. I would like to use the setup from FREE version. Thank you.
