White ink is pretty much like all the other colors of tattoo ink, but it does seem a tad more opaque. Please note it is one of the colors that fades the fastest over time and which can be damaged by sunburning quite easily. I've known folks who've burnt white ink right out of their artwork with just one or two sunburns. Also, depending on the color of your skin, sometimes white tattoos don't show up very well or don't look all that white.
