Thanks for all the info. Makes prefect sense along with default RGB color numbers being assigned, i thought is was something along those lines. I'll deal with it for now, just was trying to get textures to match up as close as possible. They maybe better off a little different anyways for raw materials to manufactured ones.
Now just to figure out how to best make the ore overlays for the raw block. Since the overlay doesn't really detect the fade out of color and just finds the hard edge to paste the default color in. Back to brainstorming and work on the pack. Ill make sure I post some more images as soon as I have fixes made and my show world assembled.
