I am, first and foremost, so appreciative of the attention the owner, Katherine, gave in helping me find the right formula and color. I sent her a picture and, to my surprise, she noticed a slight olive tone to my skin. With her assistance, Viviana ended up being a great color that I would never have guessed was my color on my own. It tones down the redness I have, while blending with my neck and chest. I love the weightless feel of this foundation that gives great natural-looking coverage, without the cakiness I've experienced with so many others.
