Tint Navigation Icon in Toolbar : <p>How to tint menu icons is already covered a few times, like here:
<a href="https://stackoverflow.com/questions/28219178/toolbar-icon-tinting-on-android">Toolbar icon tinting on Android</a></p>

<p>Additionally to this solution there is still the problem of the navigation icon. 
Applying a Theme(Overlay) to your Toolbar just tints the text and the whitelisted icons (see: <a href="https://stackoverflow.com/a/26817918/2417724">https://stackoverflow.com/a/26817918/2417724</a>)</p>

<p>If you set a custom icon (which happens to be quite easy the case, as you need to change it if you don't want to display the default back arrow) then this custom icon does not get tinted.</p>

<p>How do you handle your Icons then?
All my icons are per default black and I don't want to have special white versions just to use them in the Toolbar then.</p>
