Pink balls will be used to limit play lost to bad light in Test matches in a trial introduced by the International Cricket Council.
The pink ball has been used in day-night Test matches since 2015, but has not before been interchangeable with the traditional red ball during matches.
The ICC announced the introduction of the trial on Monday and is still working through a timeline for its introduction.
According to BBC Sport, the ICC has not specified the length of the trial, but said it will work with the Marylebone Cricket Club (MCC) to research lighting technology for match officials and venues.
Also, both teams involved in a Test have to give prior agreement that a pink ball can be used in instances of bad light.
This pink ball trial was one of several recommendations from the Chief Executives Committee that were approved by the ICC Board at a meeting in Ahmedabad on Sunday.
It also approved the allowance of head coaches to enter the field of play during drinks breaks in T20 internationals.
Additionally, Cricket Canada has had its ICC membership suspended with immediate effect over “serious breaches of its membership obligations”.
Meanwhile, the governing body has “expressed concern regarding the growing expanse of franchise cricket” and announced the formation of a committee with the aim of harmonising the international and franchise calendars.
