You can try this code

static char[] hexDigits = {
         '0', '1', '2', '3', '4', '5', '6', '7',
         '8', '9', 'A', 'B', 'C', 'D', 'E', 'F'};



public static string ColorToHexString(Color color)
        {
            byte[] bytes = new byte[4];
            bytes[0] = color.A;
            bytes[1] = color.R;
            bytes[2] = color.G;
            bytes[3] = color.B;
            char[] chars = new char[bytes.Length * 2];
            for (int i = 0; i < bytes.Length; i++)
            {
                int b = bytes[i];
                chars[i * 2] = hexDigits[b >> 4];
                chars[i * 2 + 1] = hexDigits[b & 0xF];
            }
            return new string(chars);
        }
