The other YSL Rouge Pur Couture Vernis à Lèvres Glossy Stain I picked up is Corail Fauve #12. Most of my views (re: packaging, smell, texture etc) will be the same as my review for Corail Aquatique, so I will keep this brief and more of a photo review.
Corail Fauve is a very bright coral with a hint of red, and not for the faint hearted.
In these side by side photos, you can see the difference between the similar sounding shade names. Corail Aquatique is more of a day-to-day colour that would suit most people, whereas Corail Fauve is for statement lips. In the below photo, I tried to capture the stain left by these two shades. It's ot obvious in this photo but the Corail Fauve stain is more intense than the Corail Aquatique due to the pigmentation in the product.
