To colour specific points in plot using labels

I have a plot, in which all the points have been labelled.

Is there any way, by which I can specify an array of few points using that label and colour them differently in the plot.?

In what manner were the labels created? If they're text objects, use the handles and you can set any properties you wish.

Sometimes these are the places to use the figure editor and manually do one or two and see what it is that you're fooling with if you're inexperienced w/ handle graphics.
