N scale layout , "Coloring the whole project"

 The next step was  to  wash the  rocks  with  oil paints . Various mixes of grey , brown , black   for the darked areas  and  light grey and white for the highlights   provide  a nice finish .

    Here I put some  grass on the hill . The  rocks  now seem better  and the overall area is now more colorful !
