There really aren't any alternatives, just setting the marker as a representative color of my design.

Hey @CosminPerRam,

Just for clarification, you need to change the default marker to React Native View?
or you want to change the color of the current default icon?

[CosminPerRam]

I want to change it.

noted, I'll keep that in mind for the next release.
