Take one CND colour and add Additive Effects and Pigments to create an endless number of colourpops to choose from:
Far left is CND Shellac Purple Purple with, from second left to right, Blue Heaven Effect, Spectrum Shimmer Effect, Pink Gold Sparkle Effect, Amethyst Flash Pigment Effect, Periwinkle Twinkle Glitter and Winter Blue Glitter.
My favourite is Purple Purple with Pink Gold Shimmer Effect (middle colourpop) – which is yours?
