Chanel Royallieu #58 Rouge Coco Shine is currently a Limited Edition Chanel.com exclusive. It's a relatively new release in the US and I would describe it as a lovely pale cool-toned pink. In the tube it appears slightly faded with a slight greyish undetone. If you look closely, you will see the prettiest tiny micro-sparkles. As soon as I opened the tube, I was worried it would be too pale on the lips. Royallieu Rouge Coco Shine is actually quite a bit paler than I anticipated, but I was pleasantly surprised to find that it is sheer enough to not wash out the lips, but pigmented enough to give a soft pale wash of pink shine.
Here it is swatched on my lips, I'm a Chanel Vitalumiere Aqua in 30 now:
If you love pale pinks, you will love Royallieu. It is similar to a few other shades I have so I wouldn't say it's the most unique, however it is a pretty pink that is very wearable. Of the existing Chanel lipsticks, it's lighter/pinker than Mythic. Also shown below, Dior Urban (shown here) and Rose Comete. I find that Royallieu reminds me a bit of MAC Oyster Girl Lipglass (not shown).
Overall I think for me this fits the bill of a goof-proof go-with-everything lipstick. I will be able to wear it for any occasion and apply without needing a mirror. I love that it goes on smoothly and streak-free. I envision this looking great with a smokey eye, in particular the Prelude Quad from the fall collection!
