How can I manually assign colors to structures in my 3D Model?

Operating system: Windows 11 Pro
Slicer version: 5.10.0
Expected behavior:
Actual behavior: I imported a segmented model in .nrrd format, from MIB. After creating a model in 3D Slicer, using the model maker, most of the structures of interest were red in color (automatically assigned). This makes it difficult to comprehend the structures of interest. Is there any way I can manually assign colors to the structures in the 3D model?
