Water Willow ($16.00 for 0.01 oz.) is described as a "deep khaki green." It's a dark, forest green with cool undertones and a pearly sheen. It had good color payoff in a single stroke, and the color itself stayed on well for eight hours before migrating slightly. MAC Black Ivy (LE, $16.00) is less shimmery. Urban Decay Invasion (P, $19.00) is darker. Make Up For Ever #4K (P, $17.00) is brighter, lighter. See comparison swatches / view dupes.
I was really excited to get Water Willow (actually, I liked several of the pencils from this collection but I've got to start using up what I have before adding too much more) and made a special trip out to pick it up. It's a nice pencil - applies so smoothly and is very pigmented. The only thing is that the colour isn't as special on as I was hoping it would be. I just doesn't look unique at all and I could easily get the same look with many of the green pencils I already have.
