Using model-viewer (/examples/loading/index.html#glbModel) I want to give loading color of my model-viewer as red but I did not find anything related to that in the documentation.

Here is codepen link:

<!-- Loads <model-viewer> for modern browsers-->
<script type="module" src="/@google/model-viewer@latest/dist/model-viewer.js"></script>
<!-- Loads <model-viewer> for old browsers like IE11-->
<script type="nomodule" src="/@google/model-viewer@latest/dist/model-viewer-legacy.js"></script>

<main>
  <section class="has-dflex-center">
    <div class="lx-container-80">
      <div class="lx-row">
        <div class="lx-card bs-lg">
          <model-viewer src=".glb?1542147958948" ios-src=".usdz?v=1569545377878" poster=".png?v=1599079951717" alt="A 3D model of an astronaut!" shadow-intensity="1" camera-controls="true" auto-rotate="true" ar="true"></model-viewer>
          <p class="text"><i class="fas fa-hand-point-right"></i> This pen is a basic demo of the &lt;model-viewer&gt; web ponent. It makes displaying 3D and AR content on the web easy!</p>
        </div>
      </div>
    </div>
  </section>
</main>

You should apply custom css variables.

model-viewer {
  --progress-bar-color: red;
}

You can easily change the background color with CSS. Right now your demo has

model-viewer {
  width: 100%;
  height: 25rem;
  background-color: #70bcd1;
}

Just change the background color to red:

model-viewer {
  width: 100%;
  height: 25rem;
  background-color: #f00;
}
