A practical test before changing hair color

[NoraTox]

I am growing out my natural gray after many years of coloring and the changing contrast is making some dependable clothes look unfamiliar near my face. I want to observe the transition patiently while continuing to use most of what I own. Charcoal continues to feel practical, but a few warm beige and brown tops now seem disconnected from the cooler hair around my temples. It seems wasteful to rebuild the wardrobe before the color settles, especially because the dyed lengths will remain for quite a while. I found this personal color analysis to record fabric comparisons over time instead of relying on one photograph. Could I start with scarves in two neutrals and one accent, and should I then wait until more natural hair has grown before changing larger pieces? I am open to using existing accessories during the transition. I would value a low-purchase plan from anyone who has grown out gray.
