If you want variable names, why do you have labels = NULL in your call??

Your highlighting criterion is not clear. If you want to choose one variable and highlight points in all plots for which the value of that variable meets your criterion, then determine the indices (outside of pairs) for which this is true and write a panel function via points() to highlight. If you want to highlight points in individual plots according to the variables in the panel, then write a panel function via points()to do this. e.g. points(x,y,..., col=ifelse(x<2,'red','blue'))
