<mx:Application name="LinkButton_rollOverColor_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:ApplicationControlBar dock="true">
        <mx:Form styleName="plain">
            <mx:FormItem label="rollOverColor:">
                <mx:ColorPicker id="colorPicker"
                        selectedColor="haloBlue" />
            </mx:FormItem>
        </mx:Form>
    </mx:ApplicationControlBar>

    <mx:LinkButton id="linkButton"
            label="LinkButton"
            rollOverColor="{colorPicker.selectedColor}" />

</mx:Application>

View source is enabled in the following example.

You can also set the rollOverColor style in an external .CSS file or <mx:Style /> block, as seen in the following example:

<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2008/09/01/setting-the-roll-over-color-on-a-linkbutton-control-in-flex/ -->
<mx:Application name="LinkButton_rollOverColor_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:Style>
        LinkButton {
            rollOverColor: haloOrange;
        }
    </mx:Style>

    <mx:LinkButton id="linkButton"
            label="LinkButton" />

</mx:Application>

Or, you can set the rollOverColor style using ActionScript, as seen in the following example:

<mx:Application name="LinkButton_rollOverColor_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:Script>
        <![CDATA[
            import mx.events.ColorPickerEvent;

            private function colorPicker_change(evt:ColorPickerEvent):void {
                linkButton.setStyle("rollOverColor", evt.color);
            }
        ]]>
    </mx:Script>

    <mx:ApplicationControlBar dock="true">
        <mx:Form styleName="plain">
            <mx:FormItem label="rollOverColor:">
                <mx:ColorPicker id="colorPicker"
                        selectedColor="haloBlue"
                        change="colorPicker_change(event);" />
            </mx:FormItem>
        </mx:Form>
    </mx:ApplicationControlBar>

    <mx:LinkButton id="linkButton"
            label="LinkButton" />

</mx:Application>
