Why is my stamina bar turning Blue or Cyan ??

Rouninblade

I keep seeing this effect, don't know what it means. Bar goes from green to cyan (blue) for a battle and then goes back to being green again. Is it a bug?

This is very helpfull when you do a mission. When stamina is green, it means that the "next lvl door" is still bloked, because you still have enemies to kill. When it turns blue, you can advance to next level and the door is open.

It's not a bug. I believe it was introduced with Season 2 maps back when sprinting still drained stamina. The cyan stamina bar basically let you know when you were fully out of combat and could begin sprinting without using stamina. Otherwise, by the time you reached the next mob, you'd have no stamina left to fight.

It's still useful in those maps to tap sprint in between the faster travel dodges to instantly refill your stamina bar. As mentioned , it also let's you know if the map transition portals are open(cyan) or if you're still being followed by that lone mob in Twilight Desert or a crab is hiding in a corner in Ship Graveyard(green).

TL;DR: green=in combat, cyan=unlimited stamina(while sprinting).

When it's cyan, you can dodge spam then when your stamina is out, sprint for one second then dodge spam again. It refills your stamina.

As the others have said, it means you have instantly regenerating Stamina outside of combat. It was introduced in Season 2 to make traveling faster in those areas and to assist you in Charles' Race in Twilight Desert.
