This is why paint manufacturers always say if you are doing a big job to ensure all the paint has the same batch number.

When was working for army workshops, we would have lines of vehicles on the park, for instance a long row of Bedford MK's and although all were painted in the same shade of IRR green, every one of them looked different. This would be down to age of paint, whether it had dirt ingrained in it, wiped over with an oily rag, painted by brush which came out different to spraying, etc.

I have found a large area of SCC No.2 Brown on a vehicle that was inside and covered, this was matched by a paint company and was exactly what I wanted, but bet your life when the vehicle stands next to another they will look different!
