I am using Cartopy 0.23.0 on a Windows 11 OS installed via conda-forge, Xarray version 2023.6.0, matplotlib version 3.8.4, and Python 3.9.19 . I am seeing strange behavior that I cannot figure out where setting facecolor=’grey’ only works for some projections and also only works for Robinson projection IF I specific the central longitude. Please see the attached screenshots. When it is not working it appears that it just fills the land facecolor values with the color for the max in the colorbar.
