    <mx:ComboBox id="comboBox"
            alternatingItemColors="['red', 0x00FF00, '#0000FF']">
        <mx:dataProvider>
            <mx:Array>
                <mx:Object label="One" />
                <mx:Object label="Two" />
                <mx:Object label="Three" />
                <mx:Object label="Four" />
                <mx:Object label="Five" />
                <mx:Object label="Six" />
                <mx:Object label="Seven" />
            </mx:Array>
        </mx:dataProvider>
    </mx:ComboBox>

</mx:Application>

View source is enabled in the following example.

You can also set the alternatingItemColors style in an external style sheet or <mx:Style /> block, using the following snippet:

ComboBox {
    alternatingItemColors: #FF0000, #00FF00, #0000FF;
}

Or you can set the alternatingItemColors style using ActionScript, as seen in the following snippet:

comboBox.setStyle("alternatingItemColors", ["red", 0x00FF00, "#0000FF"]);
