How to change the color of buttons in Alert in Ionic2

Question

Can I change the color of the Alert (Ok, Cancel) buttons in Ionic2? Can we use a property cssClassto give buttons color?

.buttonCss{
    button{
        color:#e74c3c !important;
    }
}

The code above gives the same color to the Ok and Cancel buttons, as shown below.

But I need to get the following result (both shoulb in buttons are different colors),

Any help is appreciated ...!

Edit 1: function added showAlert()

    showAlert(title, message, yesHandler, noHandler, caller) {
    let alert = this.alertCtrl.create({
        title: title || "Please Confirm",
        message: message,
        cssClass:'buttonCss',
        buttons: [
            {
                text: 'Exit',
                handler: () => yesHandler(caller)
            },
            {
                text: 'Cancel',
                role: 'cancel',
                handler: () => noHandler(caller)
            }
        ]
    });
    alert.present();
}

Answer 1

1) The first option, just using a class to warn, and a CSS style rule for each button

showAlert(title, message, yesHandler, noHandler, caller) {
    let alert = this.alertCtrl.create({
        title: title || "Please Confirm",
        message: message,
        cssClass:'buttonCss',
        buttons: [
            {
                text: 'Exit',
                handler: () => yesHandler(caller)
            },
            {
                text: 'Cancel',
                role: 'cancel',
                handler: () => noHandler(caller)
            }
        ]
    });
    alert.present();
}

And then:

.buttonCss {

    button.alert-button:nth-child(1){
      color: red;
    }

    button.alert-button:nth-child(2){
      color: green;
    }
}

Thus, the first button ( nth-child(1)) will be red, and the second button ( nth-child(2)) will be green.

2) , , cssClass ,

showAlert(title, message, yesHandler, noHandler, caller) {
    let alert = this.alertCtrl.create({
        title: title || "Please Confirm",
        message: message,
        cssClass:'buttonCss',
        buttons: [
            {
                text: 'Exit',
                cssClass: 'exit-button',
                handler: () => yesHandler(caller)
            },
            {
                text: 'Cancel',
                role: 'cancel',
                cssClass: 'cancel-button',
                handler: () => noHandler(caller)
            }
        ]
    });
    alert.present();
}

:

.buttonCss {

    button.alert-button.exit-button{
      color: red;
    }

    button.alert-button.cancel-button{
      color: green;
    }
}

you have options to add a custom class for the button using cssClass

showAlert(title, message, yesHandler, noHandler, caller) {
let alert = this.alertCtrl.create({
    title: title || "Please Confirm",
    message: message,
    cssClass:'buttonCss',
    buttons: [
        {
            text: 'Exit',
            handler: () => yesHandler(caller)
        },
        {
            text: 'Cancel',
            cssClass: 'customClass',
            role: 'cancel',
            handler: () => noHandler(caller)
        }
    ]
});
alert.present();

}

In css:

.customClass{
  color:#e74c3c !important;
 }
