Geomap and maker color


I would like to use GeoMap to plot on a map positions from different object types with one different color for each type.

In my InfluxDB database I’ve a field “ObjectColor” for the color based on this format : #RGB and R, G, B is a two-digit hex, for example #FF0000 for red color and #FFFFFF for white.

When I select in Data Layer / Marker Color / ObjectColor.last I only have the same color (blue/cyan) whatever is the color value in the field.

What am I doing wrong ?

What is the expected format for the Color in that case ?

Many thanks for your help,
