the hands changes you hands to look more like hands.
The colored spells- changes the spell icons to different colors. not sure which colors. Like orange for firebased and blue for something. Orth had made a post once with a screen capture showing this. Was pretty cool.
The Colored class, well not sure.
The colored feats/ probally like the colored spells but changes your feats.
I know, not a lot of help. Sorry
