this program genrate the opposite color using the color hex code. example ==> opposite of color #FFFFFF (white) is #000000 (black)

every 2 charcter of this code can be converted to an int between 0 to 255.

#2f4ab2 ==> red: 2f, green: 4a, blue:b2 ==> conver hex to 10 base int.

after calculating the main number int we find its complementary int.

after that convert that int into hex and concatenate them.
