What's up with the orbs?

Green = health
Blue = mana
red = ?
purple = ?

im pretty sure red is damage...

The ones in Gurgox's chamber, at least, also give you what appears to be momentary invincibility needed to survive his blast but it only lasts a couple of seconds.

How long do red and purple effects last?
