Add something like this to your CSS

 border:thick green solid;
 }
 #user_name.ng-invalid{
 border:thick red solid;
 }
 #user_name.ng-pristine{

 #user_name.ng-valid{
 border:thick green solid;
 }
</code></pre>

Based on the suggestion below by Dwijen, you can also apply this to a class.

<pre><code>.form-control.ng-valid.ng-touched{
 border:thick green solid;
}
.form-control.ng-invalid{
 border:thick red solid;
}
.form-control.ng-pristine{
 border:thick grey solid;
}

.form-control.ng-valid{
 border:thick green solid;
}
</code></pre>

I need to set original border color when user click outside input. When input focused, the border color change to red, and keep red until input validation is success.

This is a piace of my code:

<pre><code>&lt;div class="form-group has-feedback"&gt;
 &lt;input id="user_name" type="email" name="user_name" placeholder="Username" autocomplete="off" ng-model="user.user_name" required="" class="form-control burger-input" maxlength="50" focus-me="" /&gt;
 &lt;span class="fa fa-envelope form-control-feedback text-muted"&gt;&lt;/span&gt;
 &lt;span ng-show="form_submitted &amp;amp;&amp;amp; loginForm.user_name.$error.required" class="label label-danger"&gt;Questo campo è richiesto.&lt;/span&gt;
 &lt;span ng-show="form_submitted &amp;amp;&amp;amp; loginForm.user_name.$error.email" class="label label-danger"&gt;L'indirizzo e-mail dev'essere valido.&lt;/span&gt;
 &lt;/div&gt;
</code></pre>
