juice changing color after being vaped

[yppan]

I made an observation today when I poured the juice out of my tank. I wanted to change flavors so I was going to save the juice in my tank for later, I noticed that the liquid had changed colors, from brown to black. Does this indicate that I am "burning" my juice?

Possibly, but it would taste burnt if you burned it. More likely, it oxidized a bit under heat and air exposure.

Yep. If it still tastes ok, no worries. Vape away!

I concur with the above. Totally normal. Oxidation will do it!
