Change Icons in Windows 8

Hey everyone,

I think I have a simple question for all of you.

I want to change the icons on my taskbar to something flatter to better fit in with Windows 8. I'd like something monochromatic to start with. Where is a safe place to go to find icons that would be good for this purpose. Also, is changing icons the same in Windows 8 as it is in Windows 7 or is there any extra difficulty?

Thanks!
