No colour dots to tag folders. Macbook Pro, OSX 10.10.3 I have just recently bought a used Macbook Pro with Yosemite installed. So far everything seemed to work ok, except today I tried to tag a folder with the coloured dot and found it not possible. The dots are there, but they have no colour. This doesn't look right and I haven't seen anything like this before.
Has anyone encountered anything like that? I would greatly appreciate your help?

Please check the screenshot attached below.
Probably the color tags have been disabled previously or some non-color tags are enabled instead. Just open Finder -> Preferences -> Tags and enable all color tags and all non-color tags you need.
