The hardest part is to describe the colour: it is sort of greyed out lilac blue with a healthy dose of bronze coloured shimmer that shifts to green and in extreme angles to pink.
To emphasize the pink (that really is very elusive) I added one coat of Sally Hansen Pink-Grape Fruit.
|China Glaze - Choo-Choo Choose You & Sally Hansen - Pink-Grape Fruit|
Choo-Choo Choose You is quite sheer: you need a good two coats (preferably three) to get it opaque and it has the tendency to pull a bit away from the nail edge (so tippwear comes quick and easy, as you can see). I think this has something to do with the base being fairly transparent and the shimmer floating around in it: disliking the edge of the nail.......
I am going to try this one out with a creme base underneath and see how that translates (without the Sally Hansen, because that does not do it any favours I think)!
I like Choo-Choo Choose you very much, it's murky and strange, autumn like and interesting; it deserves being the must have of the collection (of the entire year perhaps?!).
