Are you a beginner at OpenGL as well? Are you familiar with glMaterial? The osg::Material StateAttribute is a wrapper around this, and provide the ability to set the colour of objects. You can attach a Material to a StateSet and attach the StateSet at the top node of your subgraph.

It depends upon what you want to achieve and how your model is put together. I know nothing about your model, and what precisely you be my colour of your model as there are multiple ways one could interpret colour changes. I also don't know how much you know about OpenGL/OSG so don't know where to start. Are you familiar with how OpenGL manages colour? Are your familiar with controlling colour via osg::Geometry? Are you familiar with osg::Material + OpenGL's glMaterial and color material? Do you want to have a single colour for the whole model? Do you want the model light, or do your want to disable lighting?

Re: [osg-users] How can I change the colour of the model?
Greetings! For what it's worth, I used code from the example osgtexture1D to paint an object I raped it into it's own node (parent of the Group Node) and now anything that is a child of that node gets painted. Hope that helps!
