Firstly, it is hard to even think that an orc would switch sides.

And it's even harder to believe that Sauron would share his secret plans to forge the one ring with an ordinary orc who then goes and tells the Elves of the plan.

The writing on this show baffles me.

The red is probably the Kings Men, while the blue is from season 1 before the split. I hope when Elendil and his sons leave Numenor, the armor from season 3 will be their permanent one. With blue robes. The fish scale while is accurate to how Tolkien described didn't win any points with fans. At least these golden cloaks armor looks like proper armor.
