What color does the text of child features become when a feature is selected in the Part Navigator?

When a feature is selected in the Part Navigator, the text color of child features changes to blue. This visual cue serves to indicate which feature is currently active or edited. The use of blue helps enhance the user experience by clearly differentiating selected elements from those that are not selected, allowing for easier navigation and management of features within the Part Navigator. The choice of color is significant because it is commonly associated with selection or highlighted status in many software interfaces.

Other colors mentioned transform part of the visual language of the interface but do not indicate selection in the same way. For instance, colors like red or green might be used in different contexts for alerts or confirmations, and black typically represents normal, unselected status. The blue color specifically denotes active selection, making it the correct answer in this context.
