How to customize colors on a XML dashboard based on status indicators?

[dsmith1988]

I am trying to create a dashboard that shows a red box around a failed or down state, and a green box around passed or up state. Currently, I am getting the dashboard, but the boxes will only show as black.

Could someone please show me what I am doing wrong?

<dashboard>
  <label>Website State</label>
  <row>
    <panel>
      <single>
        <search>
          <query>index="amazon-aws" sourcetype="aws:cloudwatchlogs" state_new=* AND site_location=*
                |eval state_new=if(state_new=="PASSED","up","down")
                |eval range=if(state_new=="PASSED","low","severe")
                |stats latest(state_new) AS state_new BY site_location</query>
          <earliest>-24h@h</earliest>
          <latest>now</latest>
        </search>
        <option name="colorBy">value</option>
        <option name="colorMode">block</option>
        <option name="drilldown">none</option>
        <option name="field">range</option>
        <option name="numberPrecision">0</option>
        <option name="rangeColors">["0x53a051", "0x0877a6", "0xf8be34", "0xf1813f", "0xdc4e41"]</option>
