How do I get ships with Different color schemes?

I see plenty of folks with the same ship as me but they have different color schemes I keep looking and looking but all i can find are stickers where and how are people getting different color ships?

Its base on sub-tier ships.For example lets take Jericho t1 ships,u start with the Axe ship,after a few ranks,u can buy the Axe-X type or Axe-X type S.The Axe-X is colored in Red,which represents Raid sub-faction,while the Axe-X type S is colored in yellow,which represents the Techs faction.

Here is the picture,hopefully this will help you to understand me :
