When I am in doubt about fabric/colors. I audition them. My method is that I fold the fabric into smaller pieces and lay them next to each other similarly as to how they would be in the block. Then I walk away from the layout and pop in a few times just to glance at it. UNLESS a fabric jumps out at me as a garish mismatch, I use them. The sum of the parts is usually so much more/better than the focus we put on individual pieces.
Give yourself permission to be creative. The fabric line you mentioned is designed to work together. The more, the merrier.
