I posted a while ago about the new Summer 2013 Limited Edition Nail Paints from Barry M, two of which are avaliable in Boots and two in Superdrug. This is the second of the Boots shades, a bright yellow. This is the least neon looking of all the colours but it's still very bright and summery.
These pictures are two coats on their own, there's no need to put this yellow on over a white to make sure it's bright enough, it does that all by itself. The yellow is a very bright, primary shade.
It's definitely a summer sort of colour, great for a cheerful burst of colour.
