Xenon is a bright, chartreuse green with warm, yellow undertones and fine golden shimmer over a more matte finish. It had semi-opaque pigmentation with a drier, moderately dusty texture that had light fallout during application and was more prone to sheering out. The eyeshadow was blendable, though, so as long as the lesser pigmentation isn't a deal-breaker, it wasn't the worst shade in the palette (which, unfortunately, isn't high praise). It lasted well for seven and a half hours on me before fading a bit.
