Hi! I'd love a recommendation from Jen the color sage and goddess!
I have always thought of my undertones as quite warm, and a makeup artist once exclaimed to me... 'you're orange!'. Prior to wearing mineral makeup, I never wore foundation of any kind and had fabulously clear adolescent skin. However I have used concealers for a long time--mostly under my eyes as I have congenitally very dark circles only exacerbated by sleep deprivation (ssh, don't tell!)--but have always found it difficult to match concealers which usually looked very ashy on my skin.
Uncannily, or perhaps even causally, I wrecked havoc on my skin when I started to pay attention to skin care about 4 summers go--namely trying to wear sunscreens every day and ending up with a disastrous mess and severe contact dermatitis. Ever since 'the sunscreens incident' I have been under the care of several dermotologists, yet my skin has remained hyper sensitive with profound and pervasive redness that may never go away. Here's to hoping... And ever since that time--and originally the Drs' suggestion as an alternative to SS and also for aesthetic reasons-- I have been wearing store-bought mineral makeup, but have never been entirely satisfied with the color selection. Also, my neck is irritation free and much sallower and lighter than my chest, which tends to pick up color from the sun and also has some red-casted irritation as well, so I'm never sure whether to aim 'matching' to my neck or my chest, but generally aim for a tone closer to my chest sans redness.
Enter Silk Naturals! I had guessed that I would find my best batch in Buttery Gold, so purchased this in excess along with the starter kit and also a sample sachet of the medium coverage base. However after going outside to mix shades, I came inside and discovered that I vastly prefer the Original base to the Medium Coverage, as the latter I found difficult to blend, blotchy, and generally too heavy. But the good news is that the coverage level of the Original is perfect for me! And blends beautifully

And Perfecting Powder is quite a stunner of a product!
After trying out several different ratios on my arm outside, I concluded that 1.5 warm gold : 1.5 buttery gold : 12 Original Ivory was my match. But when I took the color I mixed inside and applied it, I found that it looks muddy/dirty on, especially under incandescent light.... Would really like to have some advice on where to go from here.
Also, I would love it if I could make the finish (currently semi-matte?) just slightly more glowy even than the glow that dusting with PP adds. I have samples of Glow, Tempt Tryst, and Love Lure; which and how would you recommend I try these? Try more finishing powder, or mix some into the foundation directly? I am aiming for something between dewy and semi-matte, certainly not shiny, perhaps what I am describing is satin finish? Not quite sure about terminology...
Anyway, I am sorry that I have so few pics to post, as most are taken indoors and I think I am wearing mineral foundation in all of them; I'm ashamed to admit that I never leave the house without it these last few years due to the redness from irritation

and also for some sun protection. So I picked a melange of pics, and think I look like I have a very different skintone in all of them!
Really looking forward to your help, thanks in advance!
