  • Be aware if you are getting the hex value from the querystring, the hash will be URL encoded as %23. – Phillip Jan 18 '13 at 06:37

string hexValue = "#000000"; // You do need the hash
Color colour = System.Drawing.ColorTranslator.FromHtml(hexValue); // Yippee

Edit: You do actually need the hash, or the alpha value won't be taken into account. Woops!

var my col = Color.FromArgb(int x);

note you need to specify an alpha value as well (probably you want FF for this, i.e. fully opaque, so add 0xFF000000 to the colour hex value)

Can you change the values to start with FF? E.g. FFFFFFFF = white. This is to add the alpha value to the beginning.

If so, just parse the value with System.Drawing.Color.FromArgb. It takes an int where the first 8 bits are the alpha value. 255 is opaque.

To convert your string into an int, use Int32.Parse. E.g. 

String HexColourValue = "FABFAB";
System.Drawing.Color colour = System.Drawing.Color.FromArgb(Int32.Parse("FF"+HexColourValue,
                              System.Globalization.NumberStyles.HexNumber));

Make sure that HexColourValue doesn't have '#' in it.

Color.FromArgb(Convert.ToInt32( str.Substring(1), 16 ));

  • won't this give an aplha value of 0 which is transparent? – jk. Nov 19 '09 at 10:50
  • Yes, it does, if alpha is supported. You would have to use #FF123456 if you want nontransparent colors or add 0xff000000 to the conversion result. – EricSchaefer Nov 19 '09 at 13:33
