Flex ColumnSeries CSS fills not being applied

Question

I'm trying to set the fill colour of the series in a Flex (v4.6) ColumnChart using CSS. I'm currently using setStyle as I've also set the alpha value, but I understand that this is quite resource intensive so I'm thinking of not setting the alpha and just setting the colour using CSS. However, I can't get it to work using a CSS declaration something like:

mx|ColumnSeries {
fills: #FFCC33, #FF0033, #FF3333, #FF6633, #FF9933;

It works fine if I define the following styles:

    <fx:Style>
        @namespace s "library://ns.adobe.com/flex/spark";
        @namespace mx "library://ns.adobe.com/flex/mx";

        .anotherColour { fill: #CCFFB3; }

        .andAnotherColour { fill: #BBFF99; }

    </fx:Style>

and apply as follows:

                <mx:ColumnSeries 
                    xField="Month" 
                    yField="Profit" 
                    displayName="Profit"
                    styleName="anotherColour"
                    />
                <mx:ColumnSeries 
                    xField="Month" 
                    yField="Expenses" 
                    displayName="Expenses"
                    styleName="andAnotherColour"
                    />

Can anybody help please?

Thanks. Dan.
