Is it normal for a juice to change colors? I just received 4 new bottles and they're a different color of what I have left. I Vaped some of it and it seems identical so does it change with age? Curious because I hope I didn't get bad juice. Is it normal for the same identical juice to have a different color?

Yes it is normal, not only does the nic oxidize so do some flavorings. It is also common for some flavoring concentrates of the same flavor to vary in color.
It's not nicotine oxidation per se. To prove this, make up three batches of juice:
1) Just PG, VG, and colorless flavors.
2) Just PG, VG, and nic
3) PG, VG, colorless flavors, and nic
With all three stored all three at room temperature for a a few weeks:
1) will change the least, quite probably not at all
2) will change minimally, if at all
3) will probably darken to some shade of yellow, orange, or reddish.
I'm pretty confident it's an interaction between nicotine and certain flavoring components. The hue and saturation in sample 3 will vary vary on the flavorings used.

Agree, I've had some flavors (with 7mg nic) stay clear for several months.
Others will start to yellow, same time and nic concentration.
Yes, it is normal for some juices to do that and it depends (I think) on a lot of factors, including steeping time and process, I do think nicotine salts tend to stay clearer longer, some flavorings are dark in color and may darken, some juice makers even use colorants to make their juices "look" like they should "taste" which really is a practice I don't care for, I usually buy "colorless" coco for example, and it tends to stay pretty clear in my DIY experiments, whereas some storebought juices might have colorant in it.
It's not usually a cause for concern, things to do vary. Only if it turned a very strange color like bright orange, (some contaminants or bacteria can cause color changes, or frothiness) would I be worried. But overall some slight variation is normal.

Way back, my most-vaped juice was a Peaches & Cream from a local shop who would custom-mix it to my spec (65% VG, 15 mg nic). It always started out colorless, but would turn a peachy shade of bright orange after a while. I'm confident such color changes are an interaction between the nic and the some of the flavoring components.
