After painting the roof it is finally time to color the ground. This time we use the â€śdark on whiteâ€ť technique. This technique requires powdered paint and a liquid binder. Binders can be acrylic binder from the art store, technical gelatine (Hasenleim) or simply some beer with a twist off cap. In my aquaintance the beer is the most popular binder: first because after drying the paint can still be washed off with water and second because of the disposal of unused binder
The colors used depend on the type of creche. For a folkloric creche from Germany brown, two greens and some black together with some white for mixing seems appropriate. I make my green from blue and some gold ocre, see Fig 29. The typical yellows do not give nice greens for vegetation. Since the blue is such a strong pigment I keep it away from the other pigments on the pallet.
The first part is a thorough coloring of the KrippenmĂ¶rtel covering the ground with side by side. It is important to color the ground thoroughly such that all crevices and valleys become painted. One cannot put too much color on the ground since the second step will be to wash all the excess paint off with a wet â€“ not dripping â€“ sponge., see Fig 30 It is important to keep the sponge clean and change the water regularly. If the sponge contains to too much pigment it becomes the paint brush
The wet sponge takes off the pigment from the elevated parts of the ground such that a nice lively pattern develops, see Fig 31. One needs to press out the sponge thoroughly. If the sponge is too wet, it takes off too much color.
