Wow.

The billion dollar question.

There are as many answers to that question as there are eyeballs!

Your aircraft colleagues will have good advice I'm sure. Basic schemes/ colour configurations / historical / manufacturing and technical guide posts.

In the end, I'm thinking you want to be 'in the ballpark'; complete exactness is a holy grail that is unattainable for a billion reasons.

I have a Spyder color calibration system for my monitor from my previous life as a visual designer. But it is affected by the color of the lights over my bench. The time of day. What I ate for breakfast. The source of the image on my screen, the light where it was photographed, the time of day, the equipment that captured it, what they ate for breakfast!

Cheers
