Sorc - Elemental icons on enemy health bars

[RSR]

Here's a screenshot to illustrate what im talking about-

On my sorc sometimes there are fire / ice / lighting icons beneath an enemy's life bar, sometimes they're white, and sometimes they're red.

Is white a weakness and red a resistance? That's what I'm assuming but want to be certain.

okay so ive seen that a frost wraith has a yellow ice icon and a red fire icon, so now my assumption is
Yellow - Immunity
White - Resistance
Red - Weakness

Im glad someone else is wondering about this and not just me.

I've noticed that some monsters have yellow "armor" icon, and when using a skill that breaks their armor progresively, it goes from yellow to white eventually and soon after being white, the armor breaks and now the icon is red. So i'm thinking white and yellow are both resistances, being white low resistance and yellow high resistance, and then red is weakness.
