There is nothing wrong with mixing up a foundation to create your own perfect shade and/or finish. I have been mixing up my foundations for years, some of them are couple of shades too light, some have too much pink or yellow undertones and others are frankly way too dark. Even if you get consulted by a beauty counter "make-up artist", which by the way most of my foundation purchased that way were the wrong shade as I'd learn later after I get home and try it on. So you end up with a bunch of foundation bottles sitting there looking out of place. Be the creator of your own perfect custom made foundation, use one or two pumps of one foundation with less, more or equal amount of another and see what you can end up with.
Sometimes however you may find that the shade is more or less matching but the texture and finish is either too shiny, too matte, or has too much/too little coverage. This issue is also rectifiable. If mixing two foundations doesn't cut it, try mixing a foundation with a BB cream, it works wonders as I have recently discovered by trying to finish a too dark foundation that also is a touch too heavy on my skin. Classically BB creams are marketed as a stand-alone product or a primer for foundation, but truthfully speaking I love mixing a BB with a foundation and apply it that way, rather than layering it.
My favourite mix up at the moment is Rodial BB Venom Skin Tint in Capri + MAC Matchmaster Foundation in 3.0 [only god knows why I was matched with this shade, which is at least 2-3 shades darker than needed to be]. Also keep in mind that some foundations work better when applied with a brush, whilst others need to be warmed up and therefore a finger-application is more suitable, so don't give up on a foundation just yet, you may discover that sometimes a foundation mixed yourself can be better than a ready bought from the shelf!
