Match the flasher colour to the colour of water. Most of the time around Vancouver it's green. Otherwise match the flasher colour to the piece of the colour spectrum that is visible in water at the depths you are fishing. Green is good for all the depths normally fished around Vancouver. Otherwise the other flashers work well...Red ones used to be dynamite in the top 40 feet for Coho!coho_killer said:just wanna know the best color to use while trolling around vancouver for springs? i use green almost all the time never cought anything on anyother color!
