Single Value: Trellis View - how do I make a color change based on string values?

Path Finder

Hello Ninjas - I am not sure if I am having a brain fart or if I am just not grasping this. Seeking some help, please. I have searched for a good few hours now and have read several of the docs.

I have a simple index populated with REST API calls that return a single word. "alive" or "dead" as the field "state" Splunk ver 7.0.3

I am trying to build a dashboard panel that will sit on a KPI dashboard. We have a rather vanilla system, so there are no apps that would probably do this for me. The result I want for each host is a single value. The trellis view is appealing because I wouldn't have to go through using a base search (but maybe i have to) and then create multiple single values.

So a Single Value; value displayed is the "state" and the color should be representative of the state, but I see the ranges must be numerical, so I eval'd a numerical value field based on the state value called "state_sev".

The code snippet below returns the "state" but does not change colors. If I change the <option name="field"> to be "state_sev" It will display the numerical value and the correct color. So I am not understanding what I am missing to make this change color while displaying the text state. The color ranges are set in the GUI.

I tried using the rangemap function and I couldn't get it to do much different. I am fearful this might be due to trellis view. Not sure. I probably don't need all those options.

Any help would be appreciated! Thank you.

@cchimento see if one of my older answers suits your needs. It has the code for a run anywhere dashboard with Trellis and Status Indicator with data similar to yours.
