In MATLAB 2023a and onwards, you can modify the appearance, including colors and fonts, of vector basemaps. Please take a look at the following documentation page to learn how to do so:
Modifying color properties of a “basemap” is not directly supported earlier than MATLAB R2023a. A workaround involves using Web Map Services (WMS) functions to read the “basemap” from a compliant server and produce an image and raster reference object. See the following link for additional information on “wmsread” functionality and associated workflow:
The image is an array representing RGB pixels of the target “basemap.” This image representation can be modified like any other array to change pixel color.
