How to use rangemap in a "layout overlay" panel?

[crazyeva]

According to app 'Splunk 6.x Dashboard Examples', dashboard 'Image Overlay with Single Values', it's cool to display a single value on an image, Picture: http://postimg.org/image/sjvjqy5vn/
But is it possible to define color range for result values?

I added the rangemap command to its search string:

<search id="merging_queue">
          <query>index=_internal earliest=-5m
              | stats count
              | rangemap field=count high=1000-1800 elevated=1801-2000 guarded=2001-2500 default=gray</query>
          <earliest>$earliest$</earliest>
          <latest>$latest$</latest>
          <preview>
            <set token="merging_queue">$result.count$</set>
          </preview>
      </search>

and add singlevalue color range definition to its css file:

.singleValue {
    font-size: 4em;
    font-weight: bold;
.singleValue .singleResult {
  font-size: 3em;
  vertical-align: -4px;
  margin: 0px 6px;
}
.singleValue .high .singleResult {
  color: #ff7e00;
}
.singleValue .elevated .singleResult {
  color: #ffb800;
}
.singleValue .guarded .singleResult {
  color: #4da6df;
}
#image_overlay_panel #merging_queue {
   position: absolute;
   top: 430px;
   left: 292px;
}

But it seems the <preview> element will not take rangemap value

Still thanks to @ppablo_splunk, I will try not to mess up everything this time.
I found a solution myself.
in css file:

.singleValue {
    font-size: 1em;
    font-weight: bold;
}
.singleValue .green {
      font-size: 2em;
      color: #00ff00;
}
.singleValue .red {
      font-size: 6em;
      color: #ff0000;
}
.singleValue .blue {
      font-size: 4em;
      color: #0000ff;
}
#image_overlay_panel #parsing_queue {
   position: absolute;
   top: 430px;
   left: 292px;
}

in xml file:

      <search id="parsing_queue">
        <query>index=_internal
                  | stats count
                  | rangemap field=count green=0-50 blue=51-100 red=101-200 default=green
                  </query>
        <earliest>$earliest$</earliest>
        <latest>$latest$</latest>
      <preview>
          <set token="parsing_queue">$result.count$</set>
          <set token="parsing_range">$result.range$</set>
      </preview>
      </search>

and:

    <div class="singleValue">
        <div class="$parsing_range$" id="parsing_queue">$parsing_queue$</div>
    </div>

Thanks to @ppablo_splunk for your help, By another misoperation, I deleted your post about code editing suggestion. Could I reinstate it?
