The formula presented in these colors follows the tradition of what was available for tattooing many years ago, known as OLD PIGMENTS . -Some raw pigments used nowadays in tattooing, like Oranges and Browns, tend to fade when exposed to the sun for many years, but these wont. Here, they did not use any Orange, Magenta, Brown or Violet as a base, only what Solid Ink likes to call "OLD PIGMENTS". Solid Inks' "OLD PIGMENTS" are a combination of traditional methods and ingredients, and in some cases, mixed with pre-dispersed formulas. All colors are made of what they call powder pigments. -Bottles are opaque, like back in the day, you wont see the exact tones through them, we include a picture of the colors for your reference.Solid Ink is all about bold colour, solid saturation, and reliable healed results.
