 Easiest I to me is adding a second layer, but not on top of the wood 
but as a base. It's the way we print wood-designs in our factory.
 Start with a base colour, on top of that the wood pattern, in one or 
more layers, with some transparency. Now all you have to do is vary the 
colour of the base to get a differnt wood.
 Makes me think, it could be made closer to the printing method. Make a 
wood design in several layers. Eatch layer only uses gray-scale. Colour 
is given to a layer by a multiplication factor. All that would be 
needed to make another colour-way is changing the colour of the factor.
