 ==Changing an individual colour==
 Sometimes you may want to change the colour of a particular slot for some reasons, in such case you may check out the function '''SetPalRGB()''', again, let me just copy something from the AGS manual to bloat this space a bit:
-  '''SetPalRGB (int slot, int red, int green, int blue)'''
