Custom Hover and Select RadioButton in RadioGroup WPF XAML

Question

I'm trying to create a hover and select effect on a radio button within a group So far it works but if I hover on a button that has once been selected the hover effect doesn't work> Hovering on a button that hasn't previously been selected works and also the isChecked state seems to work. Also how do I deselect a radio button on click so that no button is selected within the group. Thanks for any help or pointers.

<Color x:Key="Hover" R="135" G="0" B="0" A="255" />
<Color x:Key="Default" R="40" G="40" B="40" A="255" /> 
<Color x:Key="Selected" R="0" G="255" B="0" A="255" />

<!-- // CustomRadioButton // -->
<Style TargetType="{x:Type RadioButton}" x:Key="CustomRadioButton">

Set ExitActions ColorAnimation Property - FillBehavior="Stop" -

<MultiTrigger.ExitActions>
    <BeginStoryboard>
        <Storyboard x:Name="ExitRadioButtonHover">
            <ColorAnimation Storyboard.TargetName="ToggleColor" 
                                                    Storyboard.TargetProperty="Color"
                                                    To="{StaticResource Default}" Duration="0:0:0:0.2" FillBehavior="Stop"/>
        </Storyboard>
    </BeginStoryboard>
</MultiTrigger.ExitActions>

...

<MultiTrigger.ExitActions>
    <BeginStoryboard>
        <Storyboard x:Name="ExitRadioButtonSelect">
            <ColorAnimation Storyboard.TargetName="ToggleColor" 
                                                    Storyboard.TargetProperty="Color"
                                                    To="{StaticResource Default}" Duration="0:0:0:0.2" FillBehavior="Stop"/>
        </Storyboard>
    </BeginStoryboard>
</MultiTrigger.ExitActions>
