Prometheus+Colour change based on status of multiple cluster instances status

Im using Promethus to check the status of the cluster using ‘probe_http_status_code{job=“$http_job”}’ HTTP response code

This shows multiple instances as bar graph with status as 200. i want to show a single bar with Red(if any one instance is not 200) or Green(if all the instances statuscode is 200).

pls provide some ideas on how to do it.
