I would describe 465 Singuliere as a sheer, cool-toned, bubble gum pink. When applied, I feel like it turns out more neutral than cool, but that's to be expected, especially with a sheer lipstick. This finish of this particular shade is 100% non-shimmery and slightly glossy. I don't feel this is as glossy as the likes of 578 Dior Kiss, but it still has a subtle shine. I'm actually glad it isn't a very glossy one, because I think a lot of the allure to this shade lies within the subtleties.
The reason I was originally going to pass on Singuliere is because I had already purchased (and fallen in love with) Chanel Rouge Coco Shine 56 Chance. I thought that they were too similar in color to justify having both. However, if I like something, I *really* like it, thus, must have it. Incidentally, I think that owning both is quite justifiable as 1) I do what I want and 2) 56 Chance is less cool-toned, brighter and more glossy in finish. To me, they're completely different. To others, maybe not. Either way, I highly recommend both lipsticks, as they're just so frickin' pretty.
