NARS Kalahari - and dupes?

NARS Kalahari eyeshadow duo (4g - 34€/23.50£/33$) is in the permanent range of NARS, the duo contains a frosty golden bronze with a pinkish hue and a shimmery warm medium brown. the texture of the lighter colour is a little bit dryer than of the darker tone which is really smooth and almost creamy. both shades are highly pigmented, no fall outs. they blend together beautifully for a warm daytime look, but each can be worn on it's own or even as a crease/outer corner shade in combination with a lighter colour.
the lasting power is as always very good, i never have a problem with fading or creasing with NARS eyeshadows.
i ordered this duo on asos.com (yay! free delivery) and received it within 5 days.

i have tried to swatch the duo against similar shades in my collection:

MAC Woodwinked - MAC Patina - Artdeco #208 - NARS Kalahari - MAC Sable - MAC Satin Taupe

so no dupes in this row :( but when i've put back the eyeshadows and swatched around a little bit, two other shades caught my eye that look much closer:

Artdeco #16 - NARS Kalahari - Artdeco #14
