[SOLVED] Help! My grey folders on my desktop turned orange

While playing with theme settings in the desktop background window, suddenly the look of the grey folder icons on my desktop changed into orange ones! Also the 'start-button' change from the 'Z'-logo into the orange Ubunto logo. Also the look of the three buttons at the top right of each window (close, minimize etc.) changed.

I don't like this look. I want to have my great Zorin look back!

I have tried to change the theme into ambiance, radiance, high contrast and high contrast reverse, but my favourite look, did not return.
I also used the Zorin Look Changer, but without satisfying result.

Who can help me?

I am using Zorin 6.

HI, do you have 'Ubuntu Tweak' installed? Is it up-to-date? If not, download from here:

https://launchpad.net/ubuntu-tweak/0.8.x/0.8.4

As it is a .deb package it should install with Software Center.

After installation, go to 'System Tools | System Settings' and Ubuntu Tweak should be present in the Appearance Section.

Launch it, then go to the 'Tweak' tab - then click on 'Themes - use the options to select 'ZorinOS' [NOT Zorin OS , click on 'Apply' and you should get your theme back!

Thank you Swarendor437 for your quick answer. It works! I've got my old Zorin look back! Many thanks!

No problemo! Will mark as [SOLVED]!
