Can't change color default folders yosemite 10.10.2 I've got a brand new mac with Yosemite 10.10.2
and I dislike the blue color of the folders

I'm looking for a proper way to change ALL folders's color

I've seen that http://yukiyamashina.github.io/blog/2014/10/19/how-to-change-the-color-of-default-folder-icons-in-OS-X-Yosemite/

But I can't find the folder CoreServices/CoreTypes.bundle/Contents/Resources/

Is this because I've got Yosemite 10.10.2 ?
Try candy Bar, I use it to change my icons and it works all the time. 
It's no longer supported by it's developers but the current version still works
