Thanks Michael! Yellow leaves should not be too difficult in the present 
configuration: just an intermediate pigment between green and red, and 
some more tweaking on the texture_map. I have only explored a little of 
the uv-mapping part of POVtree and that is where I want to try this 
technique out too, one way or another. For instanc,e I was thinking 
about layering the colours over the leaf image_maps, although that might 
give unexpected results.

I am not too familiar with arbaro although it is gathering dust 
somewhere on my HD ;-) For each application the approach might be different.
