title: Disable Darken Colors for UIToolBarButtons
body: <p>iOS 7 introduced the "Darken Colors" Accessibility Setting to introduce contrast. The theme of one of my clients' products uses white in the toolbar for tint with the bar being tinted a teal color. When this setting is turned on, the buttons go gray and actually reduce contrast and are hard to use!</p>
  
  <p>Is there a way to turn this off? I know there is an Apple API that lets you know the user has dark mode enabled, but it appears to always darken my UIToolBarButton's tint by 20%. I don't want this!</p>
  
  <p>Any insight or workarounds most appreciated!</p>
