Many years of working with the Genipa Americana fruit AKA Jagua, we have discovered a fascinating fact. Originally, the juice inside the fruit is cream color, almost white (when the fruit is unripe), then when exposed to the air, it gradually turns green, to blue, to black, this is when the juice has maximum stainability.
The color of the tattoo depends on a few factors; the freshness of the Jagua Ink Gel, the temperature of the skin, and the color of the skin. Jagua tends to develop on darker skin a very dark blue, almost black, while on pale skin it develops into a mid-blue.
On slightly darker skin, the Jagua Tattoo develops into a navy-blue, then gradually turns darker.
On pale skin, the Jagua Tattoo develops into a blue-ish color, the gradually turns into a navy-blue.
Generally, Jagua does not stain skin pitch black, however, it gives an appearance of a real tattoo.
