A great deal of info and desires have passed by, but I thought I would clarify what form the project is taking. Yes, the ships are gray; different hues, and with weathering & rust, but basically gray. Ships were painted in many differnt color schemes over their careers, so who is to say which one is "historically accurate".
Many artists will be represented, however all of the images will have generally consistent saturation, hue, and brightness values; this means I have darkened mine somewhat, lightened BigB's somewhat, alpha blended some bluish to mine, you get the picture.
The idea is to make a self consistent set.
The package will have every ship on a similar background (4 to 5 variants to avoid being boring), numbered correctly, shils, and in their appropriate folders; simple subfolder replacement. The package will also include a complete set of blank pallettes like the one below. If you want cammo, get Paint.net (its free) and do a simple alpha blend (an extensive internet tutorial comes with). You want Chicago blue, well then, overlay Chicago blue. That is the whole point in providing the blanks as tools.
