Hello,

There is no rule that the admit card should be colour printed. But it is better if you take colour printed admit card so that your details are clearly visible to the examiner and you will not face any issues on the exam day. The National Testing Agency (NTA) issued the National Eligibility cum Entrance Test or NEET-UG 2022 admit card at neet.nta.nic.in on July 12.  No other documents will be permitted inside the examination hall besides the NEET admit card 2022 and ID proof. Candidates must enter the exam centre according to the scheduled time slot after that no candidates will be permitted to enter

Black and white will definitely work. I carried black and white admit card for all the exams and i wasn't even questioned for this. But yeah dont forget to carry 1-2 passport size picture (coloured) of yours to the examination hall.
