frog colour is something i think i have a decent grasp on. for waters with less visibility i would think a black frog is a better idea since it will give the bass a better silhouette to hit, i think a popping frog is also better for waters with less visibility since it would be easier for them to locate. clear waters i would think you match whatever is around, green with a white belly, black bird with a yellow head, brown with a white belly. i don't think shad and bluegill patterns are the best idea for a frog since it's not what you are really trying to impersonate . stick to what you think a frog looks like in the area you're fishing, or find one if you can. i will definitely agree that pad crashers are the softest frogs which does make the hooksets easier. jackall iobee are also very soft. i would also take a look at reaction innovations swamp donkeys i've only heard good things about them.
