Finally the sawmill is painted!
We use brown colors to paint the beams and planks. We decided don´t use painted wooden, red, red, yellow, because the wood necesary to build the sawmill has been taken from the forest around the building. The Empire is full of forest, so this could be very common in Warhammer Fantasy.
Paint the river helped to us to add new colors like green. Green and brown are two colors easy to complemented together.
