Illamasqua Pivot Eyeshadow ($20.00 for 0.07 oz.) is described as a "yellow green." It's a medium chartreuse green with strong yellow undertones and a matte finish. There are a lot of chartreuse shades on the market, but this shade is less dupeable because it has a fair amount of green in it--it is more green than yellow. MAC Swimming is darker, greener. MAC Lucky Green is a little yellower and has a shimmery finish. Make Up For Ever #171 is the closest shade, though it's more vibrant, lighter, and has a frosted finish.
