I have a ComboBox with an ObjectDataProvider binding to an enum of colors. I have the enum descriptions displaying. I would like to have the ComboBoxItem background color match the designated color. I've created a converter that takes the enum value and returns the Brushes.Color. I'm trying to create a style, but I'm getting "incompatible type". Here's my XAML:

xmlns:converter="clr-namespace:FuelAnalysisTool.Converters"
