<div class="entry" style="background-color:#<umbraco:Item field="contentBackGroundColor" runat="server" />">

                    <umbraco:item runat="server" field="bodyText"></umbraco:item>

                </div>

More knowledge

Umbraco datatypes are created based on the control either shipped with umbraco or self-developed implementing IDataType interface. You can create you specific datatype with specific pre-defined values in different context in your umbraco site. For example, you can create background color 1 and background color 2 based on color picker to control colors in different areas in the template. Have fun here.
