Hey @Jiayonglai123,

please ask further questions on the GMT forum 🙂. The GitHub repositories are thought to be the place for development.

To improve the contrast to the background, you may want to add a box (-F) behind the scalebar or change the font color by adjusting the GMT defaults (FONT parameters). Please see the documentation at https://docs.generic-mapping-tools.org/6.3/basemap.html#l for details:

Note: Use FONT_LABEL to change the label font and FONT_ANNOT_PRIMARY to change the annotation font. The height of the map scale is controlled by MAP_SCALE_HEIGHT, and the pen thickness is set by MAP_TICK_PEN_PRIMARY. Optionally, use -F to place a panel behind the scale.

As Yvonne explained questions are made at the forum.
