Although quilts in this series are photographed in certain colors and fabric quantities are based on these combinations, that doesn't mean you have to re-create them in the same way. Choose colors for your quilt using your own color preferences. Most scrap quilt designs depend more on contrast of values than carefully preplanned and coordinated colors to create the design.
If you are a beginner, look at photos of completed quilts. Your reaction to them will guide you in your color choices, using your favorites as guides.
