How to convert Hexadecimal #FFFFFF to System.Drawing.Color

You can do

var color =  System.Drawing.ColorTranslator.FromHtml("#FFFFFF");

Or this (you will need the System.Windows.Media namespace)

var color = (Color)ColorConverter.ConvertFromString("#FFFFFF");

string hex = "#FFFFFF";
Color _color = System.Drawing.ColorTranslator.FromHtml(hex);

Note: the hash is important!
