      Works great, but I normally opt for the reverse of the new

Matplotlib palettes (i.e. viridis_r )

      Also I noticed that Viridis6 is reversed on the

documentation page

though it seems to not be when you call it.

np.linspace to generate a list of colours from matplotlib )

Passing a string to palette is just a convenience. You can
pass a list of colors. T he
palettes are available as a list of colors.

from bokeh. palettes
import Viridis10

Viridis10.reverse()

color_mapper = LinearColorMapper(palette= Viridis10, low=100,
high=1000)
