It's possible to set many variable from the command line options.
You can have a section at the top of the source POV file where you have 
a bunch of #declare where you can set your parameters.
You can have an INI file that sets/choose the desired 
colours/textures/images.
You can use a random stream to chose those same parameters. Great if you 
want a scene with 100 personalised ships. Just use a loop that randomly 
change the colours options for each ship.

You can have a collection of badges and insignas images that can be 
passed that way. A command line set variable, or ini file set variable, 
can then be used to chose a given image to be applied as an image_map.

You can use palleted image format (16 or 256 colours BMP, gif, PNG,...) 
and use a color_map to give any index any new value of your choosing, 
you can even use texture_map and replace specific colour with any 
pattern. Again, you can pass those via the command line.

You can use a few arrays of colours, or textures, and use some variable 
to chose some specific sets.

Toggether, those can enable you to create billions of different 
coulour/texture shemes. How about a differently decorated ship for each 
resident of the planet...?
