Hi Mário,

You can not change the color. But you can change the icon:

• Import an icon to the Images in the Interface layer.
• Add in the MarkerOptions of the marker the following:

"{
icon: '<Runtime Path of the Image>'
}
"

The Runtime Path of the Image, you can get it from the properties of the imported image.

You can find markers in here:
