title: How to change the underline color of the input component in MD Bootstrap
body: <p>So I'm using the <a href="https://fezvrasta.github.io/bootstrap-material-design/docs/4.0/bootstrap-components/input-group/#sizing" rel="nofollow noreferrer">Input Group Component</a> from <a href="https://fezvrasta.github.io/bootstrap-material-design/" rel="nofollow noreferrer">MDBootstrap.</a></p>
  
  <p>I was wondering if there's a way around for changing the color of the blank of the input field component in MD Bootstrap. Like at the moment, it looks like this (without focus):</p>

  <p>When I click on this input field, it looks like this (with focus, the color of the input field blank changes to green):</p>

  <p>The code for the this component is as follows:</p>
  
  <pre><code>&lt;div class="input-group input-group-lg"&gt;
    &lt;div class="input-group-prepend"&gt;
      &lt;span class="input-group-text" id="inputGroup-sizing-lg"&gt;Name&lt;/span&gt;
    &lt;/div&gt;
    &lt;input type="text" class="form-control" aria-label="Large" aria-describedby="inputGroup-sizing-sm"&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I was wondering if there's a way around for changing the color of the input field blank to black instead of green when we click on it. Thanks!</p>
