How to understand layers of paint

[Showdown]

Hi all,

I was doing some repairs to my deck lid (removing inappropriate carrera spoiler-for sale if anyone wants) and I was curious about the layers of paint/primer on my car.

The PO bought it white from the first owner who had the factory brown painted white.

What I see on the metal is:

A black coating
A white coating
A brown coating
A light gray coating
A brown coating
A white coating

I know the bright white is the new paint but what’s the white on the black and the gray in between the browns.

Ultimately it’s no big deal to me, I was just curious.

A previous repaint in the factory color of the decklid?

My best guess
A black coating -factory ecoat
A white coating -I see as light grey, factory primer/sealer
A brown coating -first paint job
A light gray coating -primer
A brown coating -second paint job
A white coating -third paint job
