Sinai (121CM) (2018) is a medium brown with warm undertones and a matte finish. It had rich color coverage paired with a smooth, velvety texture that was dense enough to have good adhesion to bare skin but was still very blendable on my skin. It was darker, more reddish than orange-based and was more matte compared to the original release. It stayed on well for eight and a half hours on me before fading slightly.
