Use this function:

 public SolidColorBrush GetColorFromHexa(string hexaColor)
       {
           byte R = Convert.ToByte(hexaColor.Substring(1, 2), 16);
           byte G = Convert.ToByte(hexaColor.Substring(3, 2), 16);
           byte B = Convert.ToByte(hexaColor.Substring(5, 2), 16);
           SolidColorBrush scb = new SolidColorBrush(Color.FromArgb(0xFF, R, G, B));
           return scb;
       }

Usage:

statusPanel.Background = GetColorFromHexa("#RRGGBB");

You can use ColorConverter.ConvertFromString Method.

statusPanel.Background =
      new SolidColorBrush((Color)ColorConverter.ConvertFromString("#FF010203"));
