The task is to create 1 pixel wide coloured vertical pinstripes with a sufficient number of pinstripes to span the entire width of the graphics display.



The pinstripes should either follow the system palette sequence,   or a sequence that includes:

black,   red,   green,   blue,   magenta,   cyan,   yellow,   and   white:

   after filling the top quarter, switch to a wider 2 pixel wide vertical pinstripe pattern,
   halfway down the display, switch to 3 pixel wide vertical pinstripe,
   finally to a 4 pixels wide vertical pinstripe for the last quarter of the display.
