Day-Night Tests and the Pink Ball: How They Differ from Day Tests
Day-night Test matches use a pink ball instead of the traditional red ball, and play extends into the evening under floodlights. Learn the differences in ball behaviour, conditions, and strategy that make day-night Tests unique.
Day-night Test cricket was introduced by the ICC in 2015 to attract larger prime-time television audiences and more spectators who cannot attend day sessions. Instead of the traditional red Dukes or Kookaburra ball, day-night Tests use a pink ball that is more visible under floodlights. The format has significantly changed tactical considerations.
The Pink Ball vs the Red Ball
| Aspect | Red Ball (Day Test) | Pink Ball (Day-Night Test) |
|---|---|---|
| Visibility | Good in daylight, poor at dusk | Visible under floodlights |
| Swing behaviour | Swings for 20+ overs conventionally | Swings more and for longer |
| Lacquer coating | Standard | Thicker — stays shiny longer |
| Seam | Standard seam | More prominent — stays upright longer |
| Reverse swing | Starts from ~30–40 overs | Starts later (thicker lacquer) |
| Visibility at dusk | Very poor — dangerous | Good under lights |
The 'Twilight Period' — Cricket's New Danger Zone
The most challenging phase of a day-night Test is the twilight period — approximately overs 50–80 of the day, when natural daylight fades but the floodlights haven't yet fully compensated. The pink ball can be extremely difficult to pick up during this transition period. Batting teams who find themselves at the crease during twilight are at a significant disadvantage. Captains who win the toss in day-night Tests often choose to bowl during the twilight period.
How the Dew Factor Changes Under Lights
Evening play under lights creates heavy dew on the outfield — similar to limited-overs cricket in subcontinental countries. Dew makes the ball wet and slippery, which prevents swing and makes bowling spin more difficult. Teams that chase in the second innings (playing under lights) benefit from dew that neutralises the bowling attack. This gives a significant advantage to the side batting second at night — another reason winning the toss matters enormously in day-night Tests.
First Day-Night Test in History
The first day-night Test was played between Australia and New Zealand at the Adelaide Oval in November 2015. Australia won by 3 wickets. The match attracted the largest crowd for a day-night cricket event in Australia's history. The success led to all major Test-playing nations eventually hosting day-night Tests, though some countries (notably India) initially resisted the format.
Frequently asked questions
Why is a pink ball used in day-night Tests?
A pink ball is used because the traditional red ball is very difficult to see under floodlights and in twilight conditions. The pink colour is more visible under artificial lighting while maintaining a similar weight and seam structure to the red ball.
What is the twilight period in day-night cricket?
The twilight period is the phase of a day-night Test when natural daylight is fading but floodlights haven't fully compensated — typically around 5:00–7:30pm. Batters find the pink ball particularly difficult to see during this transition, making it the most dangerous time to bat.
Does dew affect day-night Tests?
Yes — dew is a significant factor in evening sessions of day-night Tests. It makes the outfield wet, prevents ball swing, and makes the ball slippery for spinners. Teams batting second under lights benefit from dew that neutralises the bowling attack.
