They look awesome under UV lights.
Unless the white ink doesn't even show up, and you end up with a scar on your arm.
Depending on the design, some things just work much better in white.
But unfortunately, they can look bizarre on anyone who isn't a pale, freckle-free person.
On one hand, the white lace sleeve effect is practically a fashion accessory.
On the other hand, a white tattoo in a "pattern" can make you look diseased.
On one hand, you can get an inverse matching tattoo with the one you love.
On the other hand, they fade easily and turn into a blurry weird mess.
If you still live with your parents, your mom will never find it.
But she might be worried/curious when she sees your overly designed mosquito bites.
On one hand, you don't have to worry about jeopardizing any future employment opportunities.
But you might scare away a potential bedmate.
When they don't look "raised," they just give a very subtle effect.
But not even an elaborate head tattoo can be saved by white ink.
On one hand, you can play with mixing white ink with other colors.
But not if that other color is "scary shade of bloody scar."
On one hand, they tend to fade gracefully into nothing.
But you should really do your research when it comes to finding the right tattoo artist.
