I am trying to plot white graticule lines on an orthographic map. The background color is dark blue due to my choice of palette (I’m plotting sea ice). Does anyone know how to specify white graticule lines? I tried all numbers 1-18 in the pen argument for mp_graticule but none yield white lines.
Thank you,
