OCC Acacia Loose Colour Concentrate ($12.00 for 0.088 oz. / 2.5 grams) is described as a “yellow with blue-green duochrome.” It’s a light-medium gold with yellow-brown undertones and a subtle green duochrome. The duochrome is hard to catch except at just the right angles. It can be really pretty when you do catch it, though. Bare Escentuals Remix is a bit darker, more golden, and has no duochrome. MAC Treasure Hunt is paler, less yellow. Bare Escentuals Standing O is paler. Urban Decay Eldorado is darker and has no duochrome. MAC Gorgeous Gold is the closest shade I could think of, as it also has a green-ish duochrome, though it appears a little more golden with less brown in it.
