I am surprised noone has reviewed this one yet.
Firstly, the color: it is green. But not pickle green, not olive, not emerald, not forest...it's kind of, well, grassy green maybe? To my eye it's smack dab in the middle of blue/green and yellow/green. It is neither dark nor particularly light. A tad on the bright side, but not day-glos. It's just, well, green! There are no shimmers in it. I applied this on bare lashes, no white primer or other mascara. The color showed up as well as any other colored mascara tends to do (I have dark brown lashes): not screaming green but definitely there. Gives a nice soft look while still definining the lashes. The amazing part was that it neither smudged nor flaked, and it lasted ALL DAY. I was not expecting THAT from a HC mascara =) $10 sure is nice, too. Keep in mind that this didn't thicken or lengthen or anything like that, just added a nice coat of green while defining my lashes a bit. If you are a green fiend like me, this is definitely one to grab for fun.
