How do I change the color scheme of a basemap in MATLAB?

 I have a “basemap” I am using with “geoaxes.” How can I change the color of elements within the “basemap?” For example, I would like to change the background color of an ocean floor “basemap” from black to blue.

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. To access the documentation for “wmsread” functionality and associated workflow in MATLAB R2020a, execute the following command in the command window:

>> web(fullfile(docroot, 'map/ref/wmsread.html'))

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.
