So it has become obvious that green cannonballs signify player effects while pink? are for ship effects. This has raised a thought what about a blue cannonball that does water effects? here's what i thought of :)
Ink Ball : Spreads Kraken ink in the water that slows the enemy ship down and makes it impossible to see underwater.
Shark Ball : Spawns 3-5 sharks in the water around the enemy ship.
Volcano Ball : Heats the water causing the same burning damage when your ship is flooding.
Storm Ball : makes the water extremely rough around the point of impact and has lighting occasionally in the area.
thats all i had in mind for Blue water effect balls but heres some ideas for the Pink cannon ball colors.
Water Ball : fills ship with half the amount of water required to sink. (Pink)
Overboard Ball : Has the same kind of impact as a meg and throws people into the water. (pink)
Spin Ball : makes the enemy ship start to spin at a decent pace even with the anchor down. (pink)
thats all .-.
