Clair Obscur #4 is a deep, taupe-brown with warmer undertones and a matte finish. It had good color coverage in a single layer, which was buildable to full coverage with less than half of a layer on top. The texture was a bit denser and stiffer compared to the other shades, so it was a little more challenging to blend out but definitely workable. It seemed to take on the natural finish of my skin, though, so I would pair it with a primer if you have oilier skin. It wore well for eight hours on me before it started to fade noticeably.
