E-Liquid started clear ended yellow-ish

[Tanks]

So, the title says it all. I've been vaping Dekang 18mg watermelon juice in a vivi nova v3 ("VN"). I noticed yesterday that the juice in my vivi nova had changed from clear to having a yellowish tint to it. I'm not sure what's going on, it still tastes the same. It also happened to the juice I had in my VN today during work. NOTE: While at work I store my gear in an eGo "small" size case. It sat for a few hours in the tank (NOT connected to the battery) before I started vaping it (was using a mega 2.5ml carto because it's more discreet) but when my boss left I got out my VN and started vaping it even though the juice has the yellow tint again. Like I said above, it doesn't change the flavor at all as far as I can tell.

The only thing I can think of is somehow a little is getting burnt then mixing with the rest of the juice to cause the yellowish tint. What do you all think?

it's normal, nothing to worry about

Exposure to air.

Ok, cool. I wasn't too worried because the flavor didn't change but I was definitely curious. Glad to hear I'm not doing something wrong, though!

Thank you both.

There are actually two things that can cause darkening of juice in an atomizing device; the firsts is, as already pointed out, exposure to air (and light). The other is that, every time you take a hit, you are building up a bit of "crust" around the coil of the atty. When this is hit again by cool e-liquid after you release the button, some of that crust dissolves. This is especially true of the VN, Stardust, etc clearomizers because, when you tip them to keep the wicks wet, it adds a quick cool "shock" to the coil which knocks some of that crust off (not much). This crust is, as it would happen, always dark and, after time, can darken the color of your juice. Again, completely harmless but, if you notice it getting quite a bit worse, it may signal that you need to clean/dry burn or replace your coil.
