This is Battersea Park from Nails Inc
It's a khaki green creme and this is two coats with no top coat, as ever application was faultless.
Another one that looks different on the nail - perhaps it's a green trait? It's more olive tinged and dusty on the nail.
This was part of the Handbag Collection which I think was exclusive to QVC, IIRC they sold matching handbags in the same colours (I'm missing the handbag gene!)
