I think Colors feels Sidnaz is a give and take relationship where both know exactly what they are doing and are fine with it.
But Colors seems to be protecting Mahira in the other relationship mainly due to Paras' nature. These two are not shown that much in cheap poses (which incidentally will be a let down for Paras when he comes out and realizes all his effort was a waste)
