I could not find BrushConverter class in the latest Universal Windows App namespaces. Here is simple example to convert Hex string to Color class.

	//using Windows.UI
	class ColorUtil {
	// ColorUtil.FromHex("#FFAABBCC")
	public static Color FromHex(string hexStr) {
	hexStr = hexStr.Replace("#", "");
	return Color.FromArgb(
	(byte)Convert.ToInt32(hexStr.Substring(0, 2), 16),
	(byte)Convert.ToInt32(hexStr.Substring(2, 2), 16),
	(byte)Convert.ToInt32(hexStr.Substring(4, 2), 16),
	(byte)Convert.ToInt32(hexStr.Substring(6, 2), 16));
