paint colours

As you may be aware(!!!!!), we have been undertaking some renovations of drastic propoprtions. We have now come the the exterior paint work (sigh). Ideally we would have loved to have painted the whole house, and this was our original intention, but "Budget" suggests otherwise. In an effort to compromise, and seeing reason, we have decided to down-scale our original plan to give the place a major colour overhaul, and just change the trim colour instead.
The past week we have gone back and forth to the paint shop toying with a variety of colour ideas.
The current paint colour is dark green trim on murky white - unfortunately the murky white stays.
I must laugh at the names invented for some of these colours, and I do sympathise with paint shops, there are soooo many colours. But come on,...where in the world do they get names like "Kingsport Gray", "green gables", "night owl", "muskoka dusk"? Are these names suppose to excite the imagination or stir some kind of familiar recollection?
We picked "cromwell gray" to begin with, but concluded that it looked less inspiring and more like "Wet Cement". Then we moved to "Fairview Taupe", but found it to be more like the undesireable "packing tape brown". Disillusioned by the gray/browns we entertained reds, but "gypsy love" seemed more like "zit pink" and "arroyo red" appeared more like "dried tomato sauce on a hot day".
Anyway....after much deliberation we seem to have made a decision, and have decided to go with "provincial park", or "duck poo green", which I think to be more representative of both its tone and fragrance.
