Change color of mask password selector

Ok guys I found the right answer, there IS a way to customize the color of it. https://developer.android.com/reference/android/support/design/widget/TextInputLayout.html#attr_android.support.design:passwordToggleTint

setPasswordVisibilityToggleTintList(ColorStateList)

Update: You can directly add following attribute in the TextInputLayout:

app:passwordToggleTint="#FFF"

rapid3642's answer pointed in the right direction but I still needed to find out what exactly would work.

Follow these steps to change the colour of your toggle drawable:

1. Create selector_password_visibility_toggle in ~/res/color/:

   <?xml version="1.0" encoding="utf-8"?>
   <selector xmlns:android="http://schemas.android.com/apk/res/android">
       <!-- When password is shown as text, the drawable will be off_white coloured -->
       <item android:color="@color/off_white" android:state_checked="true"/>
       <item android:color="@android:color/white"/>
   
   </selector>
   

2. Add passwordToggleTintMode and passwordToggleTint to your TextInputLayout, as below:

   <android.support.design.widget.TextInputLayout
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       app:passwordToggleTintMode="src_atop"
       app:passwordToggleTint="@color/selector_password_visibility_toggle"
       app:passwordToggleEnabled="true">
   

Now your TextInputLayout will have its drawable colour changed.
