I have five or six different green correctors in my kit but I use MAC Select Cover-Up Corrector in green far more frequently over everything else.
I prefer the liquid cream texture to sticks, hard creams or powders - I use a fluffy eyeshadow brush to polish it sheerly over a red area and blend the edges, buff over liquid/cream foundation and do a final colour correct with a skintone concealer before powdering off. This is photographic-standard colour correction though; on myself I just work in colour corrector, apply foundation and powder off.
