title: How do I change the color of the captcha text?
body: <p>I am using the default captcha <code>yii\captcha\Captcha</code> in the default contact form as below:</p>
  
  <pre><code>&lt;?= $form-&gt;field($model, 'verifyCode')-&gt;widget(yii\captcha\Captcha::className(), [
      'template' =&gt; '
          &lt;div class="row"&gt;
              &lt;div class="col-lg-3"&gt;{image}&lt;/div&gt;
              &lt;div class="col-lg-6"&gt;{input}&lt;/div&gt;
          &lt;/div&gt;',
  ])?&gt;
  </code></pre>
  
  <p>How do I change the color of the text from the default blue to <code>#a2915d</code>?</p>
