These come in 18 shades, released in Autumn 2010 in Japan and March 2011 in the UK. They replace the previous Blend Lipsticks and Creamy Lipsticks, and combine the strengths of both those formulas.
Unlike the YSL stains, these do look very different on paper than on lips -- in a separate post I'll be swatching the shades I own on arm and lips and writing more about the formula. In brief: these are my favourite lipstick formula ever, and one of the few I can wear on my very dry, picky lips without lipbalm even in winter.
4 and 5 are more muted pinks: 4 Yamamomo softened by beige and mauve, 5 Suzumecha warmed and rounded by peach and rose tones.
7 and 8 are both lightly browned (toasted?) roses: 7 Asasuou is warmer, more muted and has more red, 8 Keshiaka is brighter and heavier on the pink.
Peach/Coral: 6 Umegasumi is a soft, neutral coral, 9 Hanarenga is a brighter and warmer peach. 10 Urumishu is a warm, bright "persimmon coral" (as FrontRowBeauty excellently put it) and 11 Sharegaki is its more muted sister with additional brown warmth.
Brown/Nude: 12 Hiwada is a neutral beige with balanced peach and rose tones.
13 Tsukushiiro is a warm yellow-peach beige and 14 Amairo an even warmer orange-peach beige -- both have strong brown undertones.
As do 15 Kogarecha, a cool browned rose, and 16 Akanecha, a richer, deeper browned rose with more red in its base.
Red: 17 Ichijiku is a vampy warm brick red. 18 Karakurenai is an uncompromisingly loud'n'clear neutral red.
You can see all eighteen shades on the beautiful cinnamongal here, though as with all lipsticks, they will look different depending on the skintone and the shade of your bare lips.
