Meta Gem bonus issue

So I messed around with gems to get the meta bonus but now I have crappy sockets and I don't have the bonus either.

I have 4 orange right now 3 blue and 1 purple. Don't ask me how I got that combo anyways

I have 2 yellow sockets 2 red and 3 blue as well as 1 prisimatic check my armory if you like

I'm going to pick up the justice points legs soon which add another blue and yellow socket giving me.

4 blue 3 yellow 2 red and 1 prisamatic.

If anyone would care to explain exactly how this all works I'd appreciated, or advice how to get the meta bonus with sacrificing the least amount of stats.
4 orange = 4 red
3 blue = 3 blue
1 purple = 1 blue and 1 red


5 red, 4 blue = less blue than red
