Bokeh color mapping behaves as follows :
x < 0 : 'red' # values < low are clamped 0 >= x < 33 : 'red' 33 >= x < 66 : 'green' 66 >= x < 99 : 'blue' 99 >= x : 'blue' # values > high are clamped
This is easy to implement and works as expected. However, is there a way to explicitly define a color for the clamped / extreme values which will be off the color mapping given? e.g:
x<0 : ‘black’
that is whilst keeping the cmapper for the middle range.
