I have yet to find a 'perfect' color scheme for wooden decking on a miniature. But these are the best colors I have found so far. You should experiment for a 'look' that pleases you. My current favorite wooden deck scheme is a base coat of Iraqi Sand (819) followed by a wash of Desert Yellow (977). For the wash use a very fine brush and make very short strokes in the direction of the planking. Then do the same thing with a wash of Brown Sand (876) again with very short strokes.
