White ball for test cricket?

John Mehaffey from Reuters writes:

White balls may be used when day-night test matches are introduced, according to International Cricket Council (ICC) general manager of cricket Dave Richardson.

I'm not sure about this.   Why do we need day / night test matches anyway?  From a New Zealand perspective it wont make any substantial difference to the numbers that attend Test Matches.

White balls are used successfully in day-night one-day matches but the players wear coloured clothing and black sightscreens are employed. Clothes and sightscreens have always been white in test cricket.

Coloured clothing in test matches just doesn't seem right to me.   That's the charm of the extended form of the game and retains some of the tradition that is slowly being whittled away.

ICC chief executive Haroon Lorgat told Reuters on Tuesday a switch to coloured clothing for test cricket would have to be carefully considered.

"It is a debate that we would love to engage in because I am not totally sure of removing the white clothing in test cricket," he said.

"There's a part of me that still wants to keep that. We need to apply our minds very carefully if we are going to change some fundamentals."

Agreed.
