Bought this in the shade Olive on Ebay for $3 plus shipping and handling. It's a pretty standard green color. Gentle on the eyes, but does not last long. Though it might stay better with primer on, which I have not tried.
I bought this in both Olive and Plum. They are indeed gentle: they go on smoothly and do not irritate, but their lasting powder sucks. If you merely swipe at it, half of it's gone.
I bought this pencil in slate. It goes on easily and feels pretty soft compared to other pencils. I had no sensitivity or irritation with this at all. My only complaint is the lack of color selection. They have slate (which is a dark gray and very flattering on brown eyes), brown and black. I would like to see a navy and an eggplant, but other than that, I really like this pencil!
