Changing Colours in the VisualStateManager

<VisualStateGroup x:Name="CommonStates">
  <VisualState x:Name="Normal" />
  <VisualState x:Name="MouseOver">
    <Storyboard>
      <ObjectAnimationUsingKeyFrames Duration="0:0:0" Storyboard.TargetName="Border" Storyboard.TargetProperty="Background">
        <DiscreteObjectKeyFrame KeyTime="0:0:0" Value="#FF1F6BAD" />
      </ObjectAnimationUsingKeyFrames>
    </Storyboard>
  </VisualState>
  <VisualState x:Name="Disabled" />
</VisualStateGroup>
