Select color lookup table from python

Hi,
I am displaying a label image in slicer using this two lines of code

volumeNode = sitkUtils.PushVolumeToSlicer(anno_itk, name='Annotations', className='vtkMRMLLabelMapVolumeNode')
slicer.util.setSliceViewerLayers(background=volumeNode)

Now the problem is that I want to use a color lookuptable that I already defined as a txt file in the ColorFiles folder. Is there a way to do this?
I tried this:

bgDisplay = volumeNode.GetDisplayNode()
bgDisplay.SetAndObserveColorNodeID('mylookuptable')

but it only works with some colors like green, red, etc but not with my own ones.

Thanks!

“mylookuptable” does not look like a node ID. You should do something like this:

bgDisplay.SetAndObserveColorNodeID(myColorNode.GetID())
