How does the V8 GH hatch supposed to work?

I guess it sorta depends on what color you’re trying to retrieve. In the attributes list you show, there is Display Colour, Print Colour, and then there would also be Layer Colour. But, basically the key is to use the Model Object component. Remember, these components act as “Pass Through” components which means you can use them as a constructor and/or deconstructor.

So, let’s say you wanted to find the Display Colour attribute. You would first pass your hatch parameter into a Model Object component and then use a Display Attributes component to extract the attributes associated with the display. Something like this. Does that make sense?

You would find the Print Colour under the Drafting Attributes and Layer Colour under Layer Attributes.
