You can change the style of spinner to change the spinner color.

Make a style in style.xml like below:

<style name="App_SpinnerStyle" >
        <item name="android:scrollbarThumbVertical">@color/colorAccent</item>
</style>

then in xml of spinner :

android:popupTheme="@style/App_SpinnerStyle"

Tried and tested!!
