asp.netmvc web helpers chart themeing

I have a currently silverlight graph that needs to be changed to a image graph

I can get the columns and data in there fine

however I cannot seem to figure out how to colorize the bars as below (right now I use the max 20% values as red anything between 2开发者_StackOverflow中文版0% and 80% of max is yellow and the low 20% as green)

It apparently cannot be done the themes are hardcoded (it seems)

 public const string Blue = "<Chart BackColor=\"#D3DFF0\" BackGradientStyle=\"TopBottom\" BackSecondaryColor=\"White\" BorderColor=\"26, 59, 105\" BorderlineDashStyle=\"Solid\" BorderWidth=\"2\" Palette=\"BrightPastel\">\r\n    <ChartAreas>\r\n        <ChartArea Name=\"Default\" _Template_=\"All\" BackColor=\"64, 165, 191, 228\" BackGradientStyle=\"TopBottom\" BackSecondaryColor=\"White\" BorderColor=\"64, 64, 64, 64\" BorderDashStyle=\"Solid\" ShadowColor=\"Transparent\" /> \r\n    </ChartAreas>\r\n    <Legends>\r\n        <Legend _Template_=\"All\" BackColor=\"Transparent\" Font=\"Trebuchet MS, 8.25pt, style=Bold\" IsTextAutoFit=\"False\" /> \r\n    </Legends>\r\n    <BorderSkin SkinStyle=\"Emboss\" /> \r\n  </Chart>";

Which would mean having separate series for separate colors.

It will however be possible once Microsoft releases MVC 3 Source code
