As per report the biggest difference in the red and pink ball is that the red ball is stitched with a white thread while the pink ball is stitched with a black thread. Meanwhile the red ball is used in games that end before sunset, while pink ball cricket will start in the afternoon with half of the game being played after the dew sets in and the linen in the seam absorbs the due and allows for a better grip.
Furthermore Cherry colour Wax is used on the red ball allowing the ball to swing, and gives the red ball its colour. Accordingly a PU based coat (ball polish is nitrocellulose based) is used on the pink ball, which prevents abrasions on the ball, and helps maintain its colour till 40 overs. Perhaps the seam of the pink ball is an equal mix of synthetic and linen, while the seam on the red ball is entirely synthetic.
Moreover the pink ball will assist the spinners as well. Hence if you notice the Kookaburra ( Red) ball, which is stitched by a machine, it doesn’t help spinners much after 40-45 overs. Perhaps as per the cricket laws stated by the Marylebone cricket Club, any international and first-class ball red, pink or even white has to weigh between 156 and 162 grams. So in terms of weight they are the same. Moreover the only big difference is that we use lacquer on pink balls so that they don’t lose their colour, while using wax on the red ones and the bowlers have a 10-15% bigger advantage with the pink ball than they have with any other.
