title: Customizing the 'back' arrow color in Actionmode with appcompat-v7
body: <p>My main theme is based on <code>Theme.AppCompat.Light</code> as follows:</p>

  <p>In <em>actionmode</em> I'd like to see white title/subtitles with a white back arrow. I've been able to set the title and subtitle text colors to white, but the back arrow remains black. This issue only occurs in places where I'm using the SupportActionbar and not the toolbar (the back arrow in toolbar is white).</p>
  
  <p>This is my toolbar in ActionMode.</p>

  <p>This is the actionbar in ActionMode. Same phone, same app, same themes, just a different activity.</p>

  <p>I can't find anything in the themes that would determine this color. According to the source, the icon is <code>@drawable/abc_ic_ab_back_mtrl_am_alpha</code>, which is white, so something must be tinting it. Where does this black-ish color come from?</p>
