A:
I recommend sticking with the basics for my lizard presentations.
For fish the gin clear waters of the north I would recommend a green pumpkin or a water-mellow.
For the more stained colored waters or late day/early morning I would recommend a black, pumpkin, or green pumpkin again.
There or many different various and colors in lizards. I would recommend starting with the basics and ask the bodies of water best know fishing store what they think. You can also go a little further with researching different lake bait fish and forage. Just because maybe a lizard is not a main item on the fishes food chain you can fool the fish with a different coloed lizard. An example is that if you have a pumpkin colored lizard and a main forage on a body of water for the time of the year has a hatch of brown crayfish you can fool the fish with the lizard. They may get used to seeing the traditional colored crayfish but a different bait such as the lizard looks "cool" and the fish may give it a try!
I hope this help and good luck with your learning!
