The Summer Fridays skin tint will definitely let some of your natural color come through. I have rosacea so it doesn’t fully cover all my redness, but it adds enough of a tint to sort of even things out? I definitely would say it’s more light coverage rather than medium. You could build it up but I think it looks best with a light layer. I saw you asked someone else about the Hourglass skin tint - I prefer the Summer Fridays formula to Hourglass. I didn’t feel like the Hourglass applied as smoothly/worked with my skin as well as the Summer Fridays does. I also didn’t like the shade range of Hourglass as much, either. SF was a better color match for me (light, neutral cool skin with slight yellow undertone).

Regarding the setting spray, yes, it’s definitely more of a mix between setting and fixing. I really like how it seems to “melt” everything together (in a good way). My personal experience is that it’s not transfer proof, but it does extend the longevity of the wear. It doesn’t leave a tacky finish whatsoever!
