One thing about how green was my valley or in this case how green are my windows is the constraints of making things in minature. A slight greenish tint in windows for instance might not be achievable without a lot of mucking about to get it, where as a standard green used for other things is easily got, so you use what is available and it might look wrong to you. It might be but unless they get the clear green plastic specially made up will go the price of the model to cover it. Getting it dead right also in the model is going to be hard to achieve anyway as everyone see's colours different and this includes who ever works out what the think is the right recipe for the green tinted windows.
One other thing is also fully prototype colours do not sit really well on a model 87 times smaller than the original prototype, you cannot really make colours 87 times different to the real thing it just will not work, you cannot really scale down colours to any great degree. You will find this out one day by getting some real paint samples for something and then painting you model one with it, it will not look right to you, I have seen it done and it was as I stated it just did not look right, but a similar colour a shade or two either way from that colour might look more correct and less overpowering colour wise.
Also some colours just do not look right on a model, yellow or gold is one such no matter what you do there it will nearly always look wrong, so in comes the art of compromise in cases like that, you know it looks wrong but Joe Blow your best friend and fellow modeller thinks it is the Bees knees. It can also depend on the base colour that some colours go over as well a yellow over a blue will tend to give the yellow a greenish type of tinge.
Yellow goes best over a white undercoat while other colours will go perfectly well over a gray undercoat.
But as I said we all see the colours differently and light can change a colour as well even on the prototype.
