Here is a quick recap of the evolution of the Pink Ball and Day and Night Test Cricket:
* Day & Night Test Cricket is played with a pink ball.
* The pink ball was tested in a 2009 ODI game between England and Australia for women.
* In January 2010, a first-class match between Guyana and Trinidad & Tobago was played with a pink ball in Antigua.
* Later other countries also experimented with the pink ball.
* In 2014, a full round of the Sheffield Shield Games in Australia was made with a pink ball from Kookaburra.
* India experimented with Day & Night Long Form Cricket back in 1997. This year the Ranji Trophy Final between Mumbai and Delhi in Gwalior was played with a white ball under light. However, India accepted cricket day and night test very late. They turned down Australia’s offer to play a day and night test in Adelaide on their 2018-19 tour. They were the ninth friendly nation to play a test with the pink ball under lights when they hosted Bangladesh at the Eden Garden last year. India won the match with one innings and 46 runs in three days.
* The first day and night test match was played in Adelaide between Australia and New Zealand in November 2015. Australia won this match by three wickets on day three.
* Kookaburra, who makes cricket balls for all countries except India, England, Ireland and the West Indies, experimented with yellow and bright orange before reaching consensus on the color pink.
* The reason the red ball was not used for day and night testing is because it was very difficult to select the red ball under lights. It is easier to spot the pink ball under lights than the red ball. The white ball has not been preferred because it is not durable enough for test cricket.
* The core of all cricket balls (red, white and pink) is the same. For the pink balls, the leather is coated with a pink pigment.
* The pink ball usually swings more at the beginning of a game.
* The Kookaburra Pink Ball has a black seam. Kookaburra first used a dark green and white seam. They later changed it to a black stitching for the pink ball. Steve Smith, who participated in the very first day and night test against New Zealand, had said the seam needed to be more visible. Kookaburra switched to black stitching in 2016.
* The pink cricket ball has an extra layer of varnish to keep the color and last longer than the red ball.
* It takes up to 4-5 days for the pink ball to get the right shine.
