The problem here, is that ANY default pigment would be 
unusable/useless/anoying for many peoples.
In my case: There are cases when white is a good choice, other when pure 
red or green are more usefull, and usualy, pure black is perfect.

That olds true for the default pigment, finish and background.

Even for the same person, a default can be optimum in one case and next 
to unusable in another.

So, that's why there is a #default{...} directive and several background 
features.
