How to convert color name to the corresponding hexadecimal representation?

Question

For example:

blue 

converts to:

#0000FF

I wrote it as:

Color color = Color.FromName(\"blue\

Answer 1

var rgb = color.ToArgb() & 0xFFFFFF; // drop A component
var hexString = String.Format("#{0:X6}", rgb);

or just

var hexString = String.Format("#{0:X2}{1:X2}{2:X2}", color.R, color.G, color.B);
