What to breed with a pastel to make some really cool looking BPs?

Depends what kind of BEL you're talking about. There are multiple ways to make a BEL

I'm not too familiar with all the different BELs. The one I saw was pretty much ivory coloured with blue eyes.

Would only certain BELs paired with my pastel create more BELs? Or would it be rare to get more BELs out of a pastel pairing...
