Foundation matching for medium yellow-olive skintone

So after ages of living in denial, I decided finally to face the reality that lots of those nice foundation formulas I liked really didn't match me all that well. The reason this preoccupation entered my mind is that I'm looking for a good foundation for wedding photos and, as I'll likely be baring my shoulders and decollete, I super duper need my face to match my chest and neck. I gathered a bunch of samples along with the foundations I own and swatched them all on my inner arm, which is currently probably NC25-30 while my face in the fall is closer to NC35-37, but my neck and chest are a shade or two lighter and cooler yellow/more olive.

It used to be that foundations were all pink-toned, but now yellow tones are a lot more popular. However, they tend to be too orange/peach on my cool yellow/olive skin, standing out more starkly on me than some of the pink-toned foundations like Bourjois Healthy Mix 55. Also, keep in mind that my face is far darker than my inner arm and that these are all used in daily application far more sheerly than swatched here, so they aren't quite as ridiculously off as they look, though admittedly imperfect for the most part. This is the list swatched for reference: (Sorry about the bad cropping in the second image, but you didn't need to see my messy room! :P)

Missha Perfect Cover #27
Shu Uemura Nobara 754

Giorgio Armani Luminous Silk 5.75
Giorgio Armani Luminous Silk 6
Chantecaille Future Skin in Camomile
Givenchy Teint Couture in 5 Elegant Honey
MAC Face & Body in C3
Stila CC Medium (this didn't swatch well as it stays green if it's not sheered out much, but then it's hard to really see without.)





It seems to me that D&G Creamy 120 Natural Beige, ELDW Rattan, Shu Nobara 754, Givenchy Photo'perfexion 106 Perfect Pecan, KA SSE SX-11, GA Luminous Silk 6, Chantecaille FS Camomile, and MAC F&B C3 are closest undertonally to the green and/or cool yellow I want to reach, especially the exceedingly green Luminous Silk 6. This "experiment" really brought home what a dearth of olive foundations there are on the market, which is strange considering how many olive-y people there exist around my skintone. If you have any recommendations for medium yellow-olive foundations, please let me know!

Giorgio Armani ETK quad 02 Terra Sienna

Thanks to some mumblings about the GA quads on MUA, I decided to try this product out. It seemed like a great neutral palette from what I'd seen online, and I liked the fact that it had a large range in terms of depth. The top two shades are shimmery and light while the bottom two are matte, far darker, and extremely pigmented. I was surprised at the depth jump between the 2nd and 3rd shades as I am more used to quads skipping in even intervals when it comes to depth. I was on the fence about this quad at first because the first look I did was subpar, in my opinion. However, I tried it again and really liked it.
