It's a bit funky when you're combining a recessive and a dominant trait.
1. We capitalize the trait which is dominant in appearance.
So, if we are discussing the construction of pastel albinos, we would designate our animals like this:

Normal: AApp (Dominant over albino, recessive to pastel)
Albino: aapp (recessive albino, recessive pastel)
Pastel: AAPa (Dominant over albino, one copy of the dominant pastel gene)
Super pastel: AAPP (Dominant over albino, two copies of the dominant pastel gene)

For the square, you would still draw a 2x2 grid, but the components would each contain one albino and one pastel gene.

Example: Albino x pastel breeding (forgive my crude grid diagram)

____ap _|__ap__
Ap| Aapp| Aapp_
AP| AaPp| AaPp_

Results:
Aapp = het albino
AaPp = pastel het albino

Hope that helps you visualize it better!
