Currently, the default color for all models in Slicer is yellow. I wanted to implement a feature that would give different types of models different default colors, like Qt::blue for bones and Qt::red for blood vessels. Now the question is, how do I know what type of models to use for adding and where should I change their default colors?

How do you know if your model is bone or blood? From the name of the files you load them from?

Yeah, I’m doing it by file name now
