I thought of adding some real swatches (on face) so you could get an idea of how the foundations translate in the skin.

My best match is Mac F&B in white. Mac studio fix fluid NW10 ends up looking muddy-ish on my skin. It also oxidizes a bit. But what annoys me is that it fails to cover properly, and it sits epically over blemishes.

Both Mac Face & Body in White, Natural daylight

All 3 are Mac studio Fix fluid NW10
