Hopefully these swatches of some close-ish foundation matches will help both those looking for similar shades and anyone else looking to extrapolate from how colour products look on my face.
From left to right, they go from lightest coverage (medium) to heaviest (v. full). I personally don't have a use for very sheer foundations -- pigmented formulas can easily be sheered out and if my skin doesn't need much coverage, I'd rather skip foundation altogether...
1. Illamasqua Skin Base SB02 neutral pink, medium coverage
2. Addiction Dewy Glow 01 Wafers neutral yellow, medium coverage
3. Nars Sheer Glow Siberia (my bottle spontaneously flung itself at the floor today, hence the Muji pot) cool yellow, medium coverage
4. Make Up For Ever Mat Velvet+ 15 neutral, medium-full coverage
5. Paul&Joe Light Cream Foundation S 00 cool yellow, medium-full coverage (NB this has been reformulated and now contains alcohol)
6. Shu Uemura Nobara stick 784 neutral yellow, full coverage
7. Laura Mercier Silk Creme Soft Ivory yellow, full coverage
8. Graftobian HD Glamour Creme Lady Fair neutral, very full coverage
9. Kevyn Aucoin Sensual Skin Enhancer SX-1 cool yellow, very full coverage
Swatches on white paper to bring out the undertone differences
Arm swatches -- natural light
Arm swatches -- natural light, by window
Bear in mind these are very heavy swatches on my inner arm, which is paler than my face; once blended out the shade differences are less apparent.
However, being even persnickitier about foundations than I am about...everything else, even slight mismatches or textural flaws, like, make my heart ache, which is where this arsenal of primers and mixers come into play:
A. MAC Face&Body White for lightening liquids or water-based creams
B. Rouge Bunny Rouge Bronzing Glow Liquid for darkening, and to add warmth and a sheen
C. RBR Sea of Tranquility to add pink and a sheen
D. RBR Sea of Clouds to lighten and add a sheen
E. RBR Metamorphoses Primer to create a satin-matte effect and conceal pores (I also love mixing this with eyeshadows and lipsticks)
F. Suqqu Makeup Base Creamy to add pink and help foundation apply over dry, flaky skin
G. Shu Uemura Stage Performer Instant Glow nominally a primer, I use this magical pore-perfecting, yellow-tinted cream instead of foundation, topped with some spot-concealer
H. Make Up For Ever HD Primer 5 Blue to cool shades down
I. Barry M Foundation Creme White for lightening thicker creams (this is much more pigmented than MAC F&B).
You'll notice that most of these add a glow -- it seems that paler shades tend to come in formulas which are really unforgiving to my dry skin.
