First store color in DB as UIColor like this

 string color = yourBtn.BackgroundColor.ToString();

Then convert your color to UIColor as

 string hex = color.;
 nfloat red = Convert.ToInt32(string.Format("{0}{0}",hex.Substring(0, 1)), 16) / 255f;
 nfloat green = Convert.ToInt32(string.Format("{0}{0}",hex.Substring(1, 1)), 16) / 255f;
 nfloat blue = Convert.ToInt32(string.Format("{0}{0}",hex.Substring(2, 1)), 16) / 255f;
 UIColor color = UIColor.FromRGB(red, green, blue);

you need to divide string to 3 sub strings to get red,green,blue color codes.
