Because I have monolids, the defining color is really hard to see when I open up my eyes. This is a really creative product, but it probably wouldn't work as well for those of us with monolids or those with larger eye areas. The colors are very neutral and wearable to work and it's easy to apply and take on the go. I can see this product being good for beginner makeup users, people running late, or thrown in a gym bag. But it may not work out for all eye shapes and those who are perfectionists with their makeup and likes greater control over how much color goes where.
TheL'Oreal Paris' Double Extend Eye Illuminator Mascara I tried is meant to highlight brown eyes as well (in Black Quartz).
Step 1 is your basic black mascara - I found that it was very light to wear, lengthend my lashes nicely, and held my curl throughout the day. It comes off with warm water.
Step 2 is the "illuminator" - it's a bronze sparkling color meant to be applied to the ends of your lashes to give it that extra oomph. I found that on overcast days (which is every day in Seattle), you really can't see the illuminator effect.
Overall I liked the mascara (but didn't feel the "illuminator" really added to the product). It lengthened my lashes so it actually looked like I had some and did not flake or smudge throughout the day.
