There is support for the pink cricket ball because the white ones used for the shorter form of the game become discoloured and become harder to spot. So far, the reports have been mixed.

Essex batsmen Napier opined that pink ball was difficult to follow when it was hit along the ground." When it got above head height it was better."
Elite panel umpire Simon Taufel said: "It (pink ball) looks pretty good. There was a little bit of a comet trail to it but it certainly gave me a lot more information off the pitch and off the seam."
Former Kent and England bowler Min Patel, who took 1-37 for the MCC when the ball was tried at Lord's, said: "The ball didn't behave any differently, it didn't react any differently, and if anything it was a lot easier to pick up in the deep when you're fielding."
"With white clouds and white seats a white ball would have been very difficult to pick up but not in this case, the ball certainly stood out."
"The design of most cricket grounds now include white seats and if you don't get a full house then a pink ball would be far easier to see."
Plans to use an orange ball in 1989 were abandoned after they were tough to spot on TV during day-night matches. In the end, it is the TV audience and spectators who will determine the fate of the pink ball.
