Hi Hingol,
It is not as simple as that. First you need to know what fish you are after. Then you can match a lure to the fish. Then you have the task of working out how deep you want the lure to go...deep diving, shallow diving, surface lure, popper, twitcher, prop etc, etc. Then you have to pick a colour...
Here is a link to the Rapala site. Probably start with a saltwater lure, but there is no reason why a fresh water wont work.
