lol - i just bought two today, red and blue!
but the tackle shop did give me advice:
use a standard paternosta rig with star/grapnal/snapper sinker on the bottom with two 30-50cm branches - one around 50cm above the sinker and the other around 100cm above the sinker with a normal hook on one branch and the popper on teh other branch.
hope that makes sense?
they indicated that colour depended on the species, the water colour, the light conditions, nothing at all etc (i.e. 'how long is a piece of string')
