As a workaround (until #3601) is finished you can do:

``` python
import matplotlib
from matplotlib import pyplot
from xarray import DataArray
import numpy

da = DataArray(numpy.linspace(0, 1)[numpy.newaxis, :]*numpy.linspace(0, 1)[:, numpy.newaxis])

cmap = matplotlib.cm.viridis

h = da.plot.contourf(vmin=.3, cmap=cmap)

cmap = h.get_cmap()
cmap.set_under('w')

h.set_cmap(cmap)
