This question gets to the heart of the SciFi modeled dilema. What are you building a model of?
A. The original filming miniature
B. How it looked on screen
Or
C. The SF ship being portrayed as it would look to an in universe observer.
All three will be somewhat different, with color being the main starting place. Any color guides will be for the filming miniature. But they will rarely look right to your eyes, as much of the on screen color appearance came from lighting and post production manipulation.
To my eye I always think Voyager looks better with a very very light base color. A very light grey. Just a bit darker than white. The best on screen color reference in my opinion is the crash sequence in Timeless, as that is really the best on screen in universe look at the ship in what we would consider "natural lighting".
