如何在LongListMultiSelector中更改CheckBox和CheckBox刻度的颜色？ WP8

Question

Is it possible to change the CheckBox and CheckBox tick's color in LongListMultiSelector. I've tried George Nikolaides solution but I was not able to approach what I needed. Is there any other way to do this? Please can somebody explain this in a little bit more detail? if it's possible. Thanks in advance, The following is George Nikolaides solution:

Answer 1

Remember to have xmlns:toolkit and xmlns:toolkitPrimitives defined like so:

<phone:PhoneApplicationPage
    xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"   
    xmlns:toolkitPrimitives="clr-namespace:Microsoft.Phone.Controls.Primitives;assembly=Microsoft.Phone.Controls.Toolkit">

Then copy this entire mess to the <phone:PhoneApplicationPage.Resources>
