Set colors for extended colorbar

Dear CDS-Team,

during my plot of a geomap I was looking for a solution to plot values higher/lower than the colorbar range in a different color.

In this example the color for lower values (<5) should be grey and for higher values (>20) black.

My research ended with the result that there is a "set_under" and "set_over" feature to set the colors. Unfortunately my tries to include them weren't successful and Im not sure where to place them.

Or should I otherwise try to create a own colormap or somehow adjust the "YlGnBu" colormap?

Thanks and cheers,

Tim
