Usually you press your seams toward the darker fabric. If there are a lot of adjoining seams I press away from them. Sometimes it calls for opening up the seam and pressing that way.
A lot of patterns will tell you which way to press.
I press toward my bindings and my sashings. But usually toward the darker fabrics.
