I agree with this.
Also, think of the sizes you are going to be cutting the fabric into and also think of the placement of the fabrics together in the pattern. Does this make sense? For example if you are cutting fabrics into 2'' squares, think of how much of the print would show, versus when you cut it into 6'' squares. Also, which fabrics are "touching" in your pattern, to me all this makes a difference.
If you have the option (at your library perhaps), you may want to check out Carol's Doak book "Your First Quilt Book, Or It should Be, " she has a section explaining fabric colors and patterns and suggestions on combining them.
Have fun!
