Dear Kaleeswari
No. It is not at all necessary to have a colour print out of admit card. For being on the safe side please read instruction details located on the back sid of your hall ticket. If and only it is mentioned(which is highly unlikely) to take a colour print, then you should have otherwise you are good with black and white printout.
Good luck
