David Leggat with all you need to know about the pink ball day-night test.
Pink really is best
Research into developing the pink ball to first-class standard has been going on 10 years and, once it was determined pink was the best colour, there's been seven years of testing and tinkering. No ball has been studied, tweaked and adapted more than the pink one. Other colours were tested, including orange - which produced a comet-like trail on television - and green, which apparently was a no-go for those with colour blindness. Testing in England included firing balls out of a cannon into a wall to test durability. Different cuts of leather were trialled, and colours of stitching, from black to green, to white and back to green. By coating the balls with a chemical, the colour could be enhanced. Kookaburra went through 16 shades of pink to get the most suitable tint. Compared with the red and white balls, "in terms of bounce, in terms of hardness, all of those characteristics and performances, there is no difference in the performance of the [pink] ball," said Kookaburra managing director Brett Elliott.
Hard to pick the seam
Spinners like the pink ball because batsmen find it hard to pick up the seam. If they can't spot the seam clearly, it makes working out the revolutions on the ball difficult, therefore harder to play. They also feel the pink ball is easier to grip.
Help under lights
Among the imponderables about how the inaugural day-night test will play out, there is common consensus on one thing: the pink ball offers more help to the fast-medium bowlers under lights than during the day. In New Zealand's two-day match against a Western Australian XI in Perth last weekend, both seam attacks were certainly more potent at night.
Easy to spot
Television viewers won't have any issues spotting the ball. At Adelaide Oval, there may be problems for the naked eye as the ball leaves the bowler's hand and reaches the batsman, once it is about 30-40 overs old. New, it's fine. Also the ball shows up well running over the green outfield.
