Chanel Vendetta is a deep, vampy purple with red and blue shimmers. It looks purple in the bottle, but once it's on the nails, it is nearly black. Indoors, the shimmers basically disappear, leaving it looking more creme-like, but outdoors, Vendetta takes on a more glow-y quality, with the shimmers sparkling in the sunlight.
Vendetta is part of the permanent collection and is available for $25 at all Chanel counters and on chanel.com.
A reader asked how Vendetta compared to Butter London HRH. Both have the same red and blue sparkles, but that is where the similarities end. Vendetta is a very dark, blue-based purple, nearly black. HRH is brighter and more red-based. See here for my original swatches of HRH.
If you love purples as much as I do, these both have a place in your collection.
