Any idea on what a complete quarter sleeve tattoo will cost?

If i decide to get a black and grey tattoo, but later want to color it... Is this possible?  What will it end up looking like or am i going to be stuck with the black and grey forever?

I might sound dumb but what movie are you talking about?

Only the greatest movie ever made, lol 

"Hedwig And The Angry Inch"

Just dropping a post to say hello.  I've been really thinking of getting a quarter sleeve tattoo and this looked like just the place to get some real info.

I'm trying to get an idea of how long it will take me to finish a quarter sleeve tattoo if I decide to get one.

Is there a time difference between getting a color tattoo or black and grey?
