As you already know, taupe colors have both gray and brown hues in them. However, depending on a specific color, it can read browner or grayer. If you look at the Taupe Tone paint color by Sherwin-Williams, you will see it has stone gray undertones, although the first impression might be that it reads brown. In a room with cooler lighting (e.g., in a room with northern light), SW Taupe Tone will show its cooler gray hue.
