How to conceal purple under eye circles

Excuse the creepy peeping eye (left)!

One of the trials and tribulations of us make-up and beauty obsessed individuals is the curse of dark under eye circles. Let's put things into perspective before I begin: this is a real first world problem. A completely vanity-induced issue- but then again, having the knowledge to correct (or improve) this area of make-up application can give you a lot more confidence and project that you are actually part of the living world, even when you feel like a bit of a hag!
I have purple under eye discolouration which shows up splendidly through my pale skin. Using colour theory, I have learned that yellow concealer can brighten this area and counteract the purple tones. Equally, bluish tones can be corrected using peach or orange-toned concealers which I also use. I have experimented successfully with two yellow concealers recently and wanted to share my results because colour correcting is currently being talked about a lot in the beauty community. Make-up artists have been using this theory for decades, but what can the average consumer achieve with it? 
As you can see, the colour wheel shows how skin tone issues can be corrected with the opposite facing colour. There is much hype about this technique at the moment and many products are now on the market that suggest they have the potential to correct redness (green concealers), sallowness (lilac tones) and under eye circles (orange, yellow and even red shades). For under eyes, I have found a cream concealer works best for me. This is because they adhere well to the skin and pack plenty of pigment- something I need! Saying that, I am a bit crepey under the eye, so careful application to the area of concern only is how I apply. I find that careful blending with the heat of my ring finger and a small dab of powder once I have applied some Nars Creamy Radiant concealer in Vanilla works well. 
So what brands do these yellow concealers come from?
