The colors seemed to work quite well, so good job there.
The obvious problem is what to leave uncolored, but I think you still established setting well in a minimal way.
I would said the camera work would have been too jumpy without how much effort you put into the sound design.
You really lined up the visual cues with the auditory ones quite well.
Those who are hearing impaired might have less mileage though.
Thank you for making this.
