These are two superficially similar eyeshadow duos from Nars, one of which I consider a mistake and one I like very much.
The two shades (pale sage and lilac) in Egea are too similar in depth and tone and altogether too frosty. I don't care for very frosty eyeshadows on me, but it's made worse in this duo by the fact that both shades are the same, extremely shimmery texture. There's no variation in depth or texture, and when I apply it all I see is a blah of shimmer. Egea is not a duo I enjoy using because of the extreme frostiness.
Tokyo's dusty lavender is a satin finish, the brushed silver isn't too bright, and is a touch lighter than the lavender. The silver is also more of a glowing pearl finish than out-and-out frost. Although it gives the same blur of non-colour as Egea, I much prefer the finish and effect of Tokyo.
Swatched: Egea top, Tokyo bottom.
