I found Studio Fix Fluid to be quite heavy and opaque, good for hard-to-cover areas on my face, like the chin. I've never tried Full Coverage foundation, but I imagine it would be good for this as well.
I believe one of the concealers is the same formula as one of the more high-coverage foundations, but I can't for the life of me recollect which one. I'm veering towards Studio Finish, but this might be off.
A green base has definitely been my greatest joy for many years, makeup-wise. I have a way-too-jolly amount of pink in my chin and cheeks: I'm the ruddiest of the seven dwarfs. Happy Capillary? Haha, anyway, I use them constantly for redness reduction. For that, I'd recommend Lorac's Oil-Free Neutralizer. It's a very pale, pastel green tint, so it's pretty impossible to accidentally apply too much and leave a noticeable green cast to your skin.
I'm currently using Bourjois's Lovely Base, and it works very well. Have to be more careful with it, but it gets the cover done. Hope this helps!
