Short answer. Navy Blue, unless your unit assigns something else. Navy is the most transferable medical scrub color in US hospitals.
Why navy
It photographs well, hides fatigue lighting, and rarely looks like a costume. Dark navy is the quieter sibling. Black is the night-shift cousin.
When not navy
When the offer letter names another color. Then that color is the only first buy.
