is there any requirement for uploading coloured photo with colour background?
Are you asking for JEE Main?
You should have a scanned image of your photograph.The photograph should be colour or b/w (but clear contrast) with name of the candidate and date of taking the photograph printed on it.
It should be without cap or goggles. Spectacles are allowed.
Polaroid photos are not acceptable.
Candidates with unclear photograph are liable to be rejected.
Candidates may keep 6-8 identical photographs in reserve for use atthe time of entrance examination,Seat Allocation Processand Admission.
Good Luck!!
