Android change color of error validation text field

Question!

If you take a look at the picture you can see the error text AND the text field go purple when I use setError() on the text field. I would like to make this RED like its supposed to be, does anyone know how to change this?

Purple text field

In your styles.xml file, you can create a custom style which uses @android:style/TextAppearance
