Am currently wearing this, and it is the third Vinylux colour I've tried - I think its my favourite so far. The colour seems to alternate between a true velvety purple and a royal blue. It is also very deep, in the sense that there are a lot of very tiny glitter or shimmer particles (the polish is smooth, got rough like glitter) in iridescent shades that really give this colour a life of its own.
In terms of application, you really need to shake Vinylux colour bottles well before application and perhaps again halfway through. It also seems best to apply the both the colour and top coat in fairly thick layers. People have complained that Vinylux shows up all the imperfections on the nail. It sort of does but applying in thick layers counters this.
Will be buying more colours! 123
