I also have very good color vision.
For me it heavily depends on the context. For example I have spent some time working out a color palette for my wardrobe, so now the colors I use there are heavily associated for me.
Without any context, it’s similar to your grouping, except for the second group: oranges go nearly all to the reds, yellows go to the greens, browns go to black and greys.
For what it’s worth, while there certainly are public bathrooms with stalls from floor to ceiling, the most common design does have gaps between the floor and the stall (at least here in Germany). Just not as big as the gaps in the US. You’d have to get uncomfortably close to the floor of a public bathroom to see anything. And no gaps between the door and the walls.
