I want to change the color of the TEXTs on my form from an xml document. i know i need to use system.drawing.color somewhere.

string scolor = "#6633aa";
int red = Convert.ToInt16(scolor.Substring(1, 2),16);
int green = Convert.ToInt16(scolor.Substring(3, 2),16);
int blue = Convert.ToInt16(scolor.Substring(5, 2),16);
label1.ForeColor = Color.FromArgb(red, green, blue);
