You can use the FrameworkElement.SetResourceReference method:

MSDN: http://msdn.microsoft.com/en-us/library/system.windows.frameworkelement.setresourcereference.aspx

Provided your xaml has this:

<TextBlock x:Name="TB">

You can write this in the code behind:

TB.SetResourceReference(BackgroundProperty, "ColorA");

You can use this:

YourControl.Style = this.FindResource(NameOfYourStyleForThisControl) as Style;

You can override ColorA inside it s parent by doing this

<TextBlock.Resources>
    <Background x:Key="ColorA">your color</Background >
<TextBlock.Resources>
