I'm not certain if this is how its supposed to be displayed, but ever since the patch, my health bars have looked like this.

In the pics, the one with both ryze and shy is how it looks on colourblind mode.

The other two is ally and enemy display for normal mode.

As you can see, no matter what mode I'm on, champion health bars are blue.

In normal mode, nothing changes except I lose the border around champ health bars, and enemy minions get a red health bar. There is no differentiation between blue and purple team on normal mode.

This is making it really difficult for me to tell who is ally and who is enemy. I asked a friend if his were blue also, and he said his were red, which I assume is the correct display- as they were before the patch.

How can I fix this?

I'm having the same issue. It really screws me over in team fights, having to take that extra second or two to discern enemy or ally in a cluster of champions in a bush. How do we get the red health bars back?

I'm having the same problem. Did either of you download Perb UI before this patch? I think that may be the problem for me.

Yeah, I realized that I had never uninstalled Perb from a while back. Attempted a repair, but it did not solve the issue. In fact, after doing the repair and turning CB mode off, all I had were massive blue squares above players. Attempting a complete re-install, should fix the issue.
