Ninjas wear black. But the colored ninja wore a different color to vs the rest of the ninja. Their reasons were their reasons. What color ninja do you know of?(To make it official spam the colors you know have to be what you're capable of) I just know Purple and Red. [I heard of green, white, orange and gray but I do not know what those can do or even do do do.]

Since I brought up other colors anyways I will enthuse you by telling you the rest of the ninja things I keep knowledged: While it may be true that illustrations and some movies show spiked-climbing palm attatchments/foot attatchments, reed blow-guns, shuriken, and riding ontop of animals I only like the black ninja that becomes a shinobi after being the Master Assassin; two katanas against the colored ninja. 

The legends of rumors go in many ways- up to New York City, Chicago, east and west sides, excetra, excetera, whatever. . . I also like the black katana. Yo, I'm totally going to get me one and cut a lit black candle dispelling all that voodoo mumbo jumbo demonic magic(k) flames. BACK TO THE TOPIC: grapple hooks, sais, juttes- Captain/Vice Admiral Smoker's long jutte in One Piece, mad respect. That Sword Hunter from rurouni kenshin with the sword whip also [i][u]kiiiilllller[/u][/i]... Ninja blade whips are real now. Guy on youtube is - I'll have one too-SMOKE BOMB-
