Kendj, I use Mac Studio C6. I have quite pale skin with yellow undertones.
have you tried C7, its a shade or 2 darker than the C6. I used to use the NC45 Sheer powder as they got rid of the 'C' powder range. I stopped using the NC45 as even though the colour was alright, the tone was wrong, its not as yellow as the 'C' range.
I love this powder so much!!! It gives great coverage. I use it to set my powder, or just by itself. You do have to becareful not to apply too much, cuz itcan look powdery, or cakey, but if I do, I spray some fix + on my face, and problem solved. MAC put their Studio Fix Powder Plus Foundation to the ultimate test of seeing how long it wears and, not surprisingly, the formula lasts for a full 12 hours! This one-step powder and foundation gives skin a smooth and even ultra-matte finish with medium-to-full buildable coverage - with a velvety texture that allows skin to breathe. Colour: C6 Studio Fix is a powder and foundation in one that combines good coverage with ease of application. Designed to be used dry, the powder and pigments create a matte, velvety texture. (only available in Studio Fix Foundation) W - Stands for warm. So best for pinkish skin. NW - Stands for Neutral warm. Pink beige skin. If you have irish in your blood you could be W or NW. Ive found MAC foundations to be so easy to apply. Unlike most foundations it doesnt dry as quickly so its very much easy to blend and smooth out.
I've incl some infor for you from MAC:
Free shipping Studio Fix Powder Plus Foundation. A one-step pressed powder and foundation that gives skin a 12-hour ultra-matte finish while controlling shine and without causing acne.
Studio Fix Conceal And Correct Palette
To understand our colors a little better, here is a breakdown of our foundation codes:
C - cool (original) - golden yellow undertones (these colors will have a single
digit after the 'C')
N - neutral (original) - neutral blend of pink & yellow
C - cool (new) - yellow/olive (these colors will have a 2-digit number after the
'C')
NC - neutral cool - neutral yellow beige
NW - neutral warm - neutral pink beige
The number that follows the letter(s) denote the depth of the shade. The higher
the number, the deeper the color.
The shades are consistent across all products (for example: NC15 in the STUDIOFIX will match the same complexion as the MATTE in NC15), however because each product generally has different coverage and finish, the shade may end up looking different on the skin (eg: the FULL COVERAGE may look lighter (due to its opaque coverage) than say the SATIN (which will show the skin's color due to
its sheer to medium coverage).
