Hi,  
I want to change the color of Nth Fidutial of a vtkMRMLMarkupsFiducialNode on a python script (As in Markups Module =\> Advanced =\> Display Properties =\> Selected Color)

I can modify the color of the entired list through the markups display node, but I didn’t find a method to change the color of a fiducial in the List.

Thanks for your help!  
Sara

The colors are specified for the whole list, so there’s not per-fiducial color. But you can set the selected state on a per-fiducial basis and assign different colors to selected and non-selected fiducials. Or you could use different lists with different colors.
