Color for dependency view

HI Experts,

Need suggestion regarding color for icons in dependency view.

So by view we can see all impacted services whenever example a CI is down will it be red by itself or we need to customise for this color to make happen.

OR if maintenance is going on for a CI , can that show GREY color or whatever.

What i wanted to ask in forum is color change is feasible any admin configurations or not feasible.?

Thanks
