+1VP if the die I used to select the shipping phase matched the color of the planet as well.
Any shipper can be used, it doesn't have to be the one used to select the phase. The way you describe it there it sounds like only one shipper would ever count for bonus vps.
I have settled a blue planet. I produced a good on that planet with a white die. Then I ship that good using a blue die. Would I get 2VP in this case?
The vp chip bonuses are independent of each other. +1 vp if the die representing the good matches the world, +1 if the die representing the shipper matches the world. Purple dice always match.
You'd get 2vp in your scenario.
