I have just finished off the first 3 chapters of the game, so very early going for me, and I have been able to figure out most of the complex options in the game. This is a total noob question, so be kind.
One thing that I have noticed when looking at my Ground Gear (under Main Menu : Party) is that the different gear have different colours. Some are blue, yellow, green or grey. At first I thought it might signify the Arms Manufacturer, but that is not it. What does it mean?
In the absence of evidence to the contrary, always assume you have the upper hand.
