Taupe is truly a must in every technician's eyebrow spectrum of colors. Taupe is an iron oxide base pigment and can be used on its own for the lighter eyebrow. To make this color even lighter, add a few drops of Brow Lightener, Brows Lightener/Red Out or Grey Gone Harmonizer. To darken it, add a drop of Dark Walnut. Taupe will heal into the skin as a light, greybrown.
