I work for a Magnet hospital, actually the first to achieve magnet status in NC. We do wear color-coded scrubs
, but I believe it was a policy that was in place long before the achievement of magnet status.
The hospital where I used to work in another state applied for and was granted magnet status and the employees could wear whatever color scrubs they wanted.
I don't think that uniforms demonstrate autonomy in practice, and a new uniform policy will most likely be rejected by current staff if a policy wasn't in place previously.
Things like self-scheduling, monthly shared governance meetings, and anything that is indicative of collaboration with other disciplines is more what the ANCC folks are looking for to demonstrate autonomy.
