hey @cutiko, thanks for this great code!
however,am facing a slight problem . i have a dark background on my login and so if user enters no password while signing up, it shows a red color text saying "this field cannot be empty" the problem is the shade of red is too dark to be clearly visible, so i wanted to change it.I tried

    <item name="colorError">#ffb5b5</item><!--not working-->

but this isn't working.also i wanted to change this 'eye' color (the icon that is shown on the password's edit text which,when clicked, makes the password visible.
Any Suggestions??
