Nope, no effects. The RGB numbers are as follows:
BLUE: 86,100,126 (+-10 all, depending on paint under it)
GREY: 156,156,156 (+-20 all, cuase of the little wear I painted on after, mostly just very small darker spots)
RED: 175,44,44
WHITE: 188,188,188 (+-5 all. NEVER USE TOTALLY WHITE ON ANY TEXTURE! anything thats above 220,220,220 should be a glow of a light or reflection)
RIVETS DARK GREY: 108,108,108
Black around the texture is really 0,0,0 but ON the texture it should be something between 2 and 10.
Another important part is lighting. In space, its fairly easy. Just think about the background you imagine for your scene. THen if there is a nearby sun, create a light to at like that sun, and if there are other suns not too far away too, then create those too. Most of the time these suns have different colors, set these too. Then, by setting the level of the Ambient light (in the Render->Enviroment) you can define the overall feeling of the scene. For example if you leave it at very low (black) then the render will feel dark, but probabbly more realistic, as in space there is nothing to scatter light (like in the WC movie, it was damn dark, you couldn't see half of the scene) If you just wanna show off your work, then be sure to turn that ambient up, so people can even see things that would be hidden by shadows. (like in the WC games cutscenes, you can allways see eveything)
"ambient light in max: the color ambient is set to is the darkest shadows can be when rendered with deffault max renderer"
