Okay, I have navigated the FreeStuff uploading, so now it's a matter of approval....I'll let you guys know when.

As for playing with these, one way of 'seeing' the effects of it, is to make the camera the "parent" of every object in your scene, then rotate the camera on the World z-axis.  This allows a view of all the various color gradations effecting the objects.
