Ion-md-input highlight problem

Hi, i am using ion-md-input and have trouble with highlights. It seems like whatever I pick for highlight-color the color is always the same.

<div class="list"> <ion-md-input class="login-input" ng-model="" highlight-color="balanced" placeholder="User" type="text"></ion-md-input> <ion-md-input class="login-input" ng-model="userLogin.password" highlight-color="assertive" placeholder="Password" type="password"></ion-md-input> </div>

I also found a codepen here
I tried to edit it to get diffrent highlight colors but it didn’t work as well. Can someone help me, please?
