If you check, you'll see that the red tips of her antennae were drawn using colour slot 32. Suppose you want them to alter between black and red colours endlessly throughout the ''whole game'', what we can do is, in each game loop, if the slot 32 is <font color='FF0000'>red</font> change it to <font color='000000'>black</font> (where (r, g, b) tuple equals (0, 0, 0) ) , ''else'' change it to <font color='FF0000'>red</font> (where (r, g, b) tuple equals (63, 0, 0) ). This logic can be visualised as follow: | If you check, you'll see that the red tips of her antennae were drawn using colour slot 32.
