Color change over night?

I'm still new to DIY, but I just mixed up a new test recipe for vanilla spearmint. All the component liquids are somewhat clear. I mixed in sweetener, 27mg NIC, french vanilla and spearmint and put it in a drawer. The next day it was a deep orange color!

It doesn't taste too bad, a little waxy menthol tasting... I'm hoping to develop it so that it has a nice sweet minty taste with a full body. Not sure what the next step is to get it there. Anyway has anyone seen a complete color change in less than 24 hours? I didn't expect that.

Yep. Got one I am experimenting with right now that it turns a light orange color when it is left overnight.

Everything going in is clear and it mixes clear. Nothing unusual though.

I get the orange/red color change with my PA cinnamon. Seems to be an atty killer too, but I really like the flavor.
