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

Note: the hash is important!

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");

When I convert white, I get not the white color exactly. – Darius Miliauskas Nov 10 '15 at 06:08

Remove the '#' and do

Color c = Color.FromArgb(int.Parse("#FFFFFF".Replace("#",""),
                         System.Globalization.NumberStyles.AllowHexSpecifier));

There are options available which do no require the conversion to a numeric value, this is an unnecessary step. The OP states it's a string – freefaller Aug 28 '12 at 09:02

The other solutions are converting the string into a numeric value too, they are just doing it internally. If this is a question of optimization, then performance testing would be required to see how `Color.FromArgb()` w/ `int.Parse()` compare to `ColorConvertor.ConvertFromString()` and `ColorTranslator.FromHtml()`. – jwatts1980 Apr 02 '15 at 17:47
Won't that have an alpha value of 0? – Nyerguds Nov 23 '16 at 19:40
