Chanel has recently released two new Ombre Essentielle Soft Touch Eyeshadows, always an occasion for rejoicing.
Chanel Ombre Essentielle in Twilight ($28.50 #89), part of the Sophisticated Eye Collection, is a cool candy pink:

Twilight has some sparkle and pigment. Here it is compared to Chanel Fauve (reviewed here), also released in the U.S. with the Sophisticated Eye Collection, the pink side of Chanel Irrellee Duo in Orient Express (now discontinued), Chanel Pink Lamé (a long-ago limited edition tweed effect eyeshadow, no longer available), Chanel Lotus and Chanel Sillage (reviewed here).

Swatches:

As you can see, Twilight bears the closest resemblance to Chanel Pink Lamé. Note that Twilight has more sparkle compared to Pink Lamé. No other color is similar to Pink Lamé. Also, you can see that Twilight would coordinate well with Chanel Fauve. Another set of the same swatch colors:

Because Twilight runs blue, it does not have the unfortunate tendency of some pink eyeshadows to give a “rabbit eye” effect. Like Pink Lamé, I can wear the color comfortably, preferably with Fauve or Chanel Taupe Grise (reviewed here).
I would expect that Twilight would coordinate beautifully with Chanel Ombre Essentielle Soft Touch Eyeshadow in Gris Exquise ($28.50 / no number provided). Then again, Chanel Gris Exquis is a color that will coordinate with virtually everything.

Gris Exquis is a medium matte gray, that can be softly applied to create dimension in the crease, or softly smoke out a liner.

This is the color that Chanel suggests be used with Chanel Ombres Tissees in Beige (reviewed here).
Here are some comparisons with the second layer of Le Metier de Beaute’s Splendid Frost (reviewed here), Bobbi Brown Steel (discontinued), the darkest shade of the Edward Bess Soft Smoke eyeshadow palette (reviewed here), MAC Silver Ring, Guerlain Instant d’une Emotion (reviewed here).

Another swatch set, same colors:

I’m a huge fan of gray eyeshadows (as you can probably tell from this post). Because they tend to be slightly cool, they add a little kick of drama to my warm skintone but still manage to be quiet neutrals. They work as a wash, or as a way to add depth to the crease. Overall, I did not find an exact match to Chanel Gris Exquis in my colleciton, although the second layer of Le Metier’s Splendid Frost was the closest.
The texture of Chanel Gris Exquis is excellent–it is very soft and pigmented. Unlike so many mattes that can go on chalky, Gris Exquis goes on buttery smooth. It’s an excellent quality shadow that is very versatile.
Note that Chanel has also re-released Chanel Magic Night (reviewed here), and Chanel Fauve to the U.S. market (reviewed here).
