Is anyone getting red or orange or blue spots on the screen?

Back button. And yes, except hardcore. You still spot, but they dont show up on your screen. On Core, when you spot someone an orange/red triangle appears above their head that your whole team can see.

^^Yup, color blind ON means the enemy shows orange and friendly is blue. Color Blind OFF is red, green, and blue for party.

But not on the phones! I've seen orange and blue

Even on that leaked dashboard video of the Xbox One, there was a red square.

Probably doesn't help that IW decided the party's colored text in-game should be an orange almost red. Why not stay with blue?

Spotting in normal mode is like lighting a Christmas tree with blue, yellow and specially red lights. You simply have to shoot at the red lights. hahaha
