Possibly convert the contours to a raster and then symbolize it. Use the elevation value for the raster value and you could do some interesting representation. Just another idea.
Your cell size is .0019 m (1.9 cm) -- given the extent your output raster would be huge. Suggest setting the output cell size to something like 5.0 or 10.0, or even 25.0 if you want a more general surface.
