Faulty appearance

Hi there!
As I entered my site recently I realized that the general appearance has changed. Especially the color scheme is completely different than originally defined. It used to look like your live preview on themeforest but now additional colors are being added – and I have no clue how this could happen. And in the responsive version it seems to be a real mess.
I am running on the latest version of Enfold, deactivated all the plugins, nothing changed. I also restored my whole site including database from a backup earlier – same appearance still.
Thanks for your advice, Cheers Chris
