Jasprit Bumrah says India must make "mental changes" when they face Sri Lanka in a pink-ball Test at the M. Chinnaswamy Stadium.
India hammered Sri Lanka by an innings and 222 runs in the first Test in Mohali.
Rohit Sharma's first Test as captain was one-sided, with Ravindra Jadeja claiming match figures of 9-87 and scoring a magnificent unbeaten 175.
India are strong favourites to complete a whitewash by winning a second Test in Bengaluru that starts on Saturday.
Pacemen Bumrah says they must adapt quickly to conditions in the day-night match.
He said: "There are mental changes you have to make. Growing up, we haven't played a lot with the pink ball.
"We are not used to catching the pink ball, bowling with the pink ball, and as batters, playing against the pink ball.
"Whatever little games we've played we're trying to get feedback from those games - certain ways the ball behaves under the lights, and how to adjust. We're still very new in this format. We're playing a pink-ball Test after a long time."
He added: "As professional cricketers, it is our job to adjust as soon as we can. Sometimes the pink ball reaches you sooner than you expect.
"The timing is different. In a normal Test match the ball swings more in the morning session. Here maybe the ball won't do much in the afternoon, but in the evening it could probably swing more.
"There are many such small pointers. We haven't played many day-night matches, and whatever we have done have been in different conditions. We are just trying to work on whatever little we have noticed in our limited experience."
The tourists will be without batter Pathum Nissanka, who scored an unbeaten half-century in the first innings of the opening Test but has sustained a back injury.
India welcome back fit-again spinner Axar Patel, with Kuldeep Yadav released from the squad.
Ashwin closing in on another milestone
Jadeja was the star of the first Test, earning the man of the match award and returning to the top of the Test all-rounder rankings.
Fellow spinner Ravichandran Ashwin also made a big impact, taking six wickets in the match and scoring an excellent 61.
Ashwin needs another 95 runs to reach the 3,000 landmark. When he achieves that feat, he will become only the second India player to take 200 wickets and score 3,000 Test runs.
Lakmal set for swansong
Suranga Lakmal is set to feature in his final Test at the age of 35.
The Sri Lanka seamer has signed for Derbyshire and this will be the last match of his international career.
Lakmal has taken 170 wickets in 69 Tests and he will be sorely missed by Sri Lanka.
