If you're unlucky the necessary evidence to really nail it down once and for all may not even exist at all any more. Documents lost in bombing raids, paint samples aged in various and not entirely known ways, etc. Then on top of that, not every bit painted RAL 1234 for example will end up looking the same. One manufacturer may end up having their paint a bit different form another. One batch may differ form another from the same maker. How exactly the paint was applied and dried can change things. Wartime strain on supplies and time can kick all of that into overdrive. And if you're hoping to go off of any photograph or paint chart then of course we go into all the shit that can go wrong there to distort the true colour.
Then once painted every bit and piece will start ageing differently. Some paints kept their hues well, others age rapidly (RLM 70 and 71 for example were replaced because greyed out much too fast). So that PhD-thesis you wrote figuring out what exact hue a specific vehicle had when factory fresh may not be very accurate later on in its life. Here's a Danish F35, painted a dark, glossy green all over.
Add these tow together and, well, you can have a look at this, scroll down a bit for dunkelgelb:
