Heat aura is just another way of healing yourself and Chroma already has enough armor with mods and Vex. But that's only if you don't have Rejuvenation or Life Strike or Winds of Purity or another healer in your team. That's a lot of alternatives.

Cold aura increases the effectiveness of all healing effects by increasing the effective health given by each hp, though as said earlier, Chroma can already reach tremendous amounts of armor, the aura's armor boost effectiveness is open for debate. And it gives a decent crowd control/tank control effect by slowing down the ennemies shooting at you.

I could go on with toxin and electric auras because they give equal usefulness compared to Vex armor and the rest of the kit. Just take a Tigris with your Toxic Chroma, you'll see what I'm saying.

All this to say, heat, cold, electric or toxic is just a matter of taste in the end, assuming you know how to build your chroma effectively.
