[DC Lantern Corps] What is the difference in constructs between each corps.?

Can only Green Lanterns create artificial items of constructs? Can only red's blast? Is there a particular corps that only creates weapons? Is there a particular corps that can only create peaceful constructs?

All the Corps can make anything they can imagine. Red has a hard time because rage is hard to control, but we do see the leader (who's name escapes me right now) make a construct. Blue can only make constructs when green is around however, after all hope is useless without will power.
