If you mean HashCode as in  GetHashCode    I m afraid you can t go back  Hash functions are not bi-directional  you can go  forward  only  not back   Follow Oded s suggestion if you need to get the color based on the hexadecimal value of the color

The three variants below give exactly the same color  The last one has the benefit of being highlighted in the Visual nbsp Studio nbsp 2010 IDE  maybe it s ReSharper that s doing it  with proper color   var cc1   System Drawing ColorTranslator FromHtml   479DEE     var cc2   System Drawing Color FromArgb 0x479DEE    var cc3   System Drawing Color FromArgb 0x47  0x9D  0xEE

Assuming you mean the HTML type RGB codes  called Hex codes  such as  FFCC66   use the ColorTranslator class   System Drawing Color col   System Drawing ColorTranslator FromHtml   FFCC66      If  however you are using an ARGB hex code  you can use the ColorConverter class from the System Windows Media namespace   Color col   ColorConverter ConvertFromString   FFDFD991   as Color    or         Color  ColorConverter ConvertFromString   FFCC66

This post has become the goto for anyone trying to convert from a hex color code to a system color   Therefore  I thought I d add a comprehensive solution that deals with both 6 digit  RGB  and 8 digit  ARGB  hex values   By default  according to Microsoft  when converting from an RGB to ARGB value      The alpha value is implicitly 255  fully opaque     This means by adding FF to a 6 digit  RGB  hex color code it becomes an 8 digit ARGB hex color code   Therefore  a simple method can be created that handles both ARGB and RGB hex s and converts them to the appropriate Color struct       public static System Drawing Color GetColorFromHexValue string hex                string cleanHex   hex Replace  0x       TrimStart                if  cleanHex Length    6                          Affix fully opaque alpha hex value of FF  225              cleanHex    FF    cleanHex                     int argb           if  Int32 TryParse cleanHex  NumberStyles HexNumber  CultureInfo InvariantCulture  out argb                         return System Drawing Color FromArgb argb                        If method hasn t returned a color yet  then there s a problem         throw new ArgumentException  Invalid Hex value  Hex must be either an ARGB  8 digits  or RGB  6 digits              This was inspired by Hans Kesting s answer
