colors doesn't swap jodis unless its pre-planned i.e jodis r pre planned but 2 give twist they made sum oder jodis earlier. i m talking abt most of shows on colors in past & present.
and no channel or PH ever will try 2 nip the jodi which is really popular just 4 shock treatment.it"ll b putting their feet on the axe.most of the time jodis r pre- planned even if they break earlier ones & made oder jodis permanent then its done acc. 2 script.
