he said it's called kabuki-by skin candy. i'm not sure if (given the "brand" kabuki) that just refers to the black ink-most of my work is in black because i feel that the heavy metals in many of the colored pigments are best avoided until my last kiddo is weaned. most modern, quality black inks are pretty innocuous. there are tons of materials data safety sheets, and more accessibly, consumer-and-tattoo-artist-oriented sites online that describe a rough content of different colors (example: there is no such thing as a hypoallergenic red ink.) in my view, in this as with all things, common sense applies. don't jump into a foot-high back piece in one day with bright red and green ink, for example. see how you feel about the research, consider any known allergies, trust and love your artist, go slowly, and be mindful of the level of vascularization of where you want the work done.
incidentally, the ink he recommended looks fabulous, i had NO healing problems (and ended up with emergency surgery the DAY after the largest piece-still healed gorgeously) and he uses the two tattoos that he did with it as the cover for his portfolio
