Basic mission after Chapter 9.

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?

I didn't pay a lot of atention to it, but I think it's rarity. I only remember that orange weapons are "Galactic" lol.

Thanks for that. You were correct, it appears to be the rarity of the item. Not sure if there is any additional significance to it such as a benefit to having all your gear be either yellow, or green, or ...

I am so damn sick of enemies that chase you fucking forever when you don't want to fight. Fuck off already.

And is there a command to tell your idiot comrades (who never, ever fucking revive you) to stop fighting and run? 

I don´t think so, all I can remember is an emergency escape command 

I don't even know why they even have a revive mechanic; I've played 26 hours and I've been revived once. It may as well not be there.

Well the trick is getting that 3000TP.  I guess you could stack one of your party member's arts to build that up faster?  Maybe?  Just spitballing there. 

There are also party commands to build TP (R + right during battle), equipment to maximize potential TP, and they rarely (never?) use arts that aren't in their pallete, so if you want to play it conservatively you could have one party member equipped with high TP-building weapons and with no TP-consuming arts in their pallete, at which point revival is likely. Alternatively, ordering the party to build tension will ensure one of them reaches 3k during the 30 second death period: just remember to change your orders if/when you want them to actually fight.

That's weird, Lin is always reviving me when she get to 3000 TP XDD.
