This is a related but very simple follow-up to a previous question, inspired by the comment of @marmot "Or do you want to use different grays for different planes?"
Here is what I have
This is a 8 x 8 x 8 cubic.
Suppose I like to have a 3 x 4 x 5 lattice with a darker lattice sitting at a new origin (2,2,2) of this 8 x 8 x 8 cubic. How should I do this? [It looks simple -- I just need to redraw another a 3 x 4 x 5 lattice sitting at a new origin (2,2,2).]
