Things like this always make me wonder about the scaling of color (I should look into how that works someday). When I watched TNG, I felt that the ship was painted in different shades of light grey. When I got the model, and read over the painting instructions, I learned that it was mostly "Duck Egg Blue". When painted in the colors per the instructions, I inevitably feel that the ship is blue and doesn't look anything like the ship on the TV or movie screen. I wonder if there is a guide to paint the ship to look like what you see there, and not what the production model is ACTUALLY painted in.
An example of the way the color changes from reality to what you see on screen was clearly demonstrated in the set where Troi crashes the Enterprise D into Vagra II. Watching the behind the scenes, I leaned that they had to make the trees extremely green (read florescent) to get the color right on screen (It's talked about at the 4 minute mark in the following video):
