Invisible health bars

Hello. Usually I play on healers and often have problem with invisieble health bars like this:

I can’t see hp of my teammates, on this screenshot hp is too light.

This color ususally better, but it’s bad color for sky.

Can’t see this health bar too.

I don’t understand how many hp have my teammates, 50%? 70%? I can’t see this.

And this color is good, but I can’t see hp on the ground in maps like Anubis. Furthermore, I can’t change colors of health bars in time when game was started.

And look now on this screenshot from Overwatch League:

This color contour is great. I can see hp of all teammates and enemies. Why I can’t use this contour too? Please, add this function in the game.
