I think of YSL as quite a colourful brand, and whilst they are not amongst my favourites, I always check out their collections as they usually have something interesting to add to the mix.
Moonlight blue is a deep midnight blue with a hint of shimmer and Wintergreen is a dark teal with subtle shimmer (£16.50 each)
The formula is thick and I could probably get away with one coat if I had better application (my first coat is a rush job the second an attempt to patch up the errors). It seems to set really quick so I felt like I had to apply it quickly for fear of it going patchy. Although I get no colour fade, this chips on me in 1 to 2 days so a top coat is a must (to be fair the majority of brands chip on me in this same time frame).

I do wish I could get better wear of these, I think due to the thickness my currant favourite top coat (Becca) doesn't gel with these, so I'll likely try some different top coats as I intend to wear these shades a lot as I really like these deep, jewel-toned colours.
I bought these from John Lewis
