I need to save a color as a string and be able to retrieve it. How can I do this

Here are a couple of routines that might do what you want. ColorToString
takes a color and represents it as a string that then can be passed into its
companion StringToColor routine that will take the string back into a color.
I think it works with all types of colors. You can download a test project.

public string ColorToString(Color c)
{
  string s = c.ToString();
  s = s.Split(new char[]{’[’,’]’})[1];
  string[] strings = s.Split(new char[]{’=’,’,’});
  if(strings.GetLength(0) > 7)
  {
    s = strings[1] + '','' + strings[3] + '','' + strings[5] + '','' + strings[7];
  }
  return s;
}

public Color StringToColor(string s)
{
  return (Color)TypeDescriptor.GetConverter(typeof(Color)).ConvertFromString(s); 
}
