I have currently utilised the Run status colour which closely aligns with the pool slot options. Reason to that is, run status colours are used all over the UI from a single source of truth(airflow/ui/src/utils/stateColor.ts). Just to not confuse users I kept the same colours of that.

The stateColor currently used are:

export const stateColor = {
  deferred: "mediumpurple",
  failed: "red",
  null: "lightblue",
  queued: "gray",
  removed: "lightgrey",
  restarting: "violet",
  running: "lime",
  scheduled: "tan",
  skipped: "hotpink",
  success: "green",
  up_for_reschedule: "turquoise",
  up_for_retry: "gold",
  upstream_failed: "orange",
};

One advantage of this would be when users will personalise the status colours of runs (https://airflow.apache.org/docs/apache-airflow/1.10.13/howto/customize-state-colors-ui.html) these values will also change.

If we should have a fixed colour, we can use the below options: (Open to discussion)

Open Slots	     Green
Scheduled Slots	     Gray	
Running Slots	     Blue	
Queued Slots	     Orange
Occupied Slots	     Yellow	
Deferred Slots	     Red	

Which would look like

Nice work! Left a few comments.

I would also like to play with adding an icon to each pool slot so it can be more accessible vs just via color. Doesn't have to be this PR, I just wanted to put the idea out there.

@bbovenzi Also, regarding slots icons, let me think of something, will try something COOL in upcoming PRs!
