HP Bar, different colors acording to type (minions)

It is often difficult for a summoner to be able to distinguish all his minions. If you have a clear differentiation in its HP bar (different colors) according to type would be great.
Let me explain. I have 3 Spectres, 9 Zombies, over 20 Vaal Skeletons and a totem summoning Skeletons (max. 12 skeletons). Besides that I use as a primary skill Raging Spirits... On occasions, I need my Spectres stay safe behind me, on other occasions, they attack without mercy. Sometimes, things get out of control and I do all step back, give potions and run, just let the peons (skeletons) do all the work. For my configuration, if they die they explode (nice damage), it is sometimes desirable to die, sometimes not. With over 50 minions all mixed, all with the same HP bar, it is very difficult to know exactly when it is convenient or not use potions.

The battles are fast, I can not be wasting time carefully examining HP bars and see if it is a Skeleton, a Zombie or Spectre or even a Ragin Spirit. If I do that, something bad will happen, that's for sure in Merciless.

Bars with different colors according to type of minion would be great help.

I like this idea, with all the clutter thats going on as a minion master it can become extremely difficult to keep track of ones army :)

UP!!!

Well it is a good idea, but I'd rather vote for changing color of ES bar on minions.
Blue shield bar on enemies is good because enemy health bars are red.
But blue shield bar around green health bar that minions have? It's completely invisible to me. Should be yellow or any other color that is in contrast to green; definitely shouldn't be blue.
PS. As for party members shields, their health is displayed in party corner of the screen anyway...
