"use model color for HLR/HLV in drawings"
or in other words you can have any colour you want for the model and have that colour then being used in the 2D drawing but it isn't intended to let one use several colours for different features in 1 model.
The only way around it that I can think of to try and get what you want is to save the different features as parts and thus re-create your part as an assembly.
If I'm wrong then I'm looking forward to hear what would be a better solution.
Have a nice one.
