After initially being opposed to the idea the Proteas have now agreed top play a day-night test against Australia at the Adelaide Oval in November.
Cricket Australia put a prize pool of $1 million on the line for last year's three-Test series against New Zealand as an incentive for the inaugural pink-ball fixture, and it was expected they might have to do likewise to get South Africa to agree to the game.
But the chief executive of the South African Cricketers' Association, Tony Irish, said it was the increase in pink-ball Tests being played around the globe that encouraged South Africa to dip their toes in the water against Australia come November.
"There was no financial guarantee, money is not a big issue here," Irish told Sky Sport.
"There hasn't been money offered by Cricket Australia and there was never money asked for by our players in that regard," he said.
Australia will also host Pakistan in a pink-ball Test in Brisbane in December, while India wants to also play host to New Zealand in one this year with New Zealand Cricket planning to also host matches in coming seasons.
However Irish said the confirmation of the match didn't mean the players' fears with the pink ball had been alleviated.
"The ball is a concern," he said.
"Some players will battle to see it - it will be difficult for some players.
"We got feedback from the Australian and New Zealand players from the Adelaide Test about those kind of difficulties."
