"how do i convert a color to a brush in xaml?" Code Answer

it seems that you have to create your own converter. here a simple example to start:

public class colortosolidcolorbrushvalueconverter : ivalueconverter {

    public object convert(object value, type targettype, object parameter, system.globalization.cultureinfo culture) {
        if (null == value) {
            return null;
        }
        // for a more sophisticated converter, check also the targettype and react accordingly..
        if (value is color) {
            color color = (color)value;
            return new solidcolorbrush(color);
        }
        // you can support here more source types if you wish
        // for the example i throw an exception

        type type = value.gettype();
        throw new invalidoperationexception("unsupported type ["+type.name+"]");            
    }

    public object convertback(object value, type targettype, object parameter, system.globalization.cultureinfo culture) {
        // if necessary, here you can convert back. check if which brush it is (if its one),
        // get its color-value and return it.

        throw new notimplementedexception();
    }
}

to use it, declare it in the resource-section.

<local:colortosolidcolorbrushvalueconverter  x:key="colortosolidcolorbrush_valueconverter"/>

and the use it in the binding as a static resource:

fill="{binding path=xyz,converter={staticresource colortosolidcolorbrush_valueconverter}}"

i have not tested it. make a comment if its not working.
