Android - setting the color of the action-bar overflow menu icon (3 dots)

Question

I'm trying to change the color of the action-bar overflow menu icon (3 vertical dots).

Doing some research, I found out the following does it.

    <item name="android:textColorSecondary">@color/white</item>

But the problem is that it changes color of some other UI that I'd rather not set.

Is there a way to set the color for just this icon.
