Terra Moons Siren Duochrome Eyeshadow ($8.00 for 0.05 oz.) is a light-medium green with warm, olive undertones and lighter flecks of bluish-green sparkle throughout. It was supposed to have "blue and reddish reflects," but I found hard to see them. It didn't have much shift to my eye--just a sparkling, metallic green.
The texture was smooth to the touch, moderately dense but more loosely-pressed, so it was best used with a lighter hand and a moderately dense brush to pick up product. The eyeshadow was richly pigmented and stayed on nicely for eight and a half hours but had light fallout over time.
