Depending on where, and at what range, the paintball hits you, it can be painful. As you can imagine, some body parts are more sensitive than others. Thick or baggy clothing can help to reduce the stinging sensation. Also, covering any exposed skin with gloves, hats and scarves can be a good idea. If you are hit from far enough away, or in the facemask or goggles, you may not feel a thing. Paintballs come in a rainbow of colors and when a player gets tagged with one, it leaves a bright "splat" of paint on them, indicating that they are out of the game.
