Hello,
I am using Dolphin with KVantum. As it is, the folder icons vary, showing a representation of the contents. I want the icon to just be solid blue, like the Animation folder in the attached screenshot. I looked in the KVantum manager, didn't see anything.

How do I do this?

~$ lsb_release -a
