Camera tape is 1'' cloth tape or 1'' gaffer's tape. I believe it's called camera tape because the camera dept. uses it the most, whereas gaffer's tape is traditionally 2'' black cloth tape.
Paper tape is different and is used for marking actors. You should have several colors of 1'' rolls and also a roll of 2'' black paper tape. Let's say you have 4 actors in a shot and need to mark all of them, you better have enough colors for each actor.
Get several colors. (You should have 1'' white camera tape on you at all times) white, black, red, blue, green, yellow, and get some obnoxious colors like neon yellow or neon orange(or pink if you want to be really annoying) for specialty purposes. Like if something breaks put the annoying color that you never use for anything else on it. Or if you flash a mag or some RED drive is being wonky.
For film work, if using multiple stocks, the 1st will usually assign each stock a color. 500T= red, 250T= orange, 100T= yellow, 250D= blue, 50D= green etc.
Also for Exposed Film, you'll wrap the can with 1'' black tape, that is the standard. For, short ends and re-cans, use the color designated for that stock to wrap the can and then of course write the length on 4 sides of the can for ease later.
