@pieper do you envision changing the slice view pipeline or just adding a module that can create an RGB volume from a vector volume?
@sthirumal You can create a colored image by combining any number of volumes into a single volume using custom rules by writing a couple of lines of Python code. See this example for combining two volumes into a third volume: Creating Volume from Numpy. You can modify it to create a colored volume by creating a new vector volume instead of cloning the input scalar volume.
