When I first saw Sonia Kashuk Eye Duo Down to Earth, which is a brownish green and a goldish brown, I honestly thought that maybe the two shades together where going to be extremely dark. Sometimes darker colors can possibly give the effect of having a black eye if not blended and highlighted properly. However, when I used a base color on the lid and blended the two colors in the crease it turned out beautifully, giving my eyes a natural, fabulous look. The eye shadow lasted pretty much all day with a primer, easily applied, was softer than your average shadow (which I love), and never creased.
When I applied this eye shadow duo I first chose a color that was close to my skin tone or a shade or to darker and applied it to my lid, then I applied brown from the duo to the crease and then the green towards the end of my lid blending it into the brown. This makeup application literally took a few minutes and was fun and very easy to achieve.
This Eye Duo is about $7 at Target. Have you tried it?
