I'm very new to this but learning, I am currently running 6.6.7 and not sure but when I first started with this program I had the nice colour icons on all my apps like docker and such and now I only have colour app on the new ones I download. Not sure how to start over and get back the colour icons for such things as Docker, network, pretty much any thing in system settings is black and white and very generic looking to say, unlike what it should be. Any help would be apprefciated as I like the other look with this.
