Will, without seeing the Raw it's hard to know where it has come from, either within the capture, or from your PP. I probably see colour in a totally different way as Jon puts it because of my background, the is why I choose to balance all my images first, before anything else and so I know there isn't a colour shift or they have any biases. If the light changes, colour will change too, hence treating each image on i's own merits, batch process can work, you just have to review before starting.
Yes light currently isn't great, albeit interesting in the morning around 6.45am...
