NAOH forms at the cathode giving a blue colour as it is an alkaline and CL2 will first give a red colour at anode then it will bleach that red colour as CL2 is a bleaching agent so electrolyte around anode becomes colourless. NAOH forms because everything discharged except Na+ ions and OH- ions. hope it helps wassalamu alaykum
