The steps you'de have to follow if you want a global colortable is :

1. Make your geosets indexed. i.e. use color indexes instead of colors in
your geoset. I think that if you want the colors to be indexed, you'll have
to make the other attributes indexed too (coords, texcoords, normals). For
that, you can just create an index list of one-to-one indexes.

2. Create a pfColorTable

3. Either attach it to the channel, or pfApply it at the beginning of your
draw.
