With the new theming in AppCompat, a lot of assets are tinted automatically for you via theme attributes. That has often led me to wonder "where the hell did this color come from?" You can replace your normal theme with this debug theme to help figure out the source of that color.

<item name="android:windowBackground">@color/__debugWindowBackground</item>
<item name="android:colorPressedHighlight">#FF4400</item>
<item name="android:colorLongPressedHighlight">#FF0044</item>
<item name="android:colorFocusedHighlight">#44FF00</item>
