Green shadow and pigment swatches
I did a swatch comparison of all the green shadows and pigments I have lying around. Hopefully someone finds this helpful ;]
I do not know what term I should use for my skintone (except that I am pale with mostly brown undertones instead of peach/pink ones), because I do not use MAC foundation or concealer. If it helps, the rare times I do wear foundation, I wear Lancome Magique Matte in Ivorie 2.
In each picture, the top row is the product on bare skin. The bottom row is the product over UDPP.
