Marker color is not working

[paragsiddique]

I am plotting a map using folium and gdf.explore(). However, folium markers (icons) are not showing correct color. Please help me get it fixed.

This is probably related to #2084. This has been fixed in Folium v0.19.5. Can you make sure you are using the latest version?

Thanks for sharing this. Unfortunately, it doesn’t resolve my issue. I'm running the code on Google Colab, which is using folium 0.19.5 and geopandas 1.0.1.

I created an issue for this. Fix is ready for review.
