The only other blue Prometheus spring is the MS100, so it doesn't look to be a mislabelled spring. Rather, as ILLusion said, it's perfectly normal for springs to want to pop out sideways when you have the shell open.
BTW, remember to have the tighter coils facing towards the rear when installing. Otherwise you'll have FPS issues.
