Scleral tattooing is the practice of tattooing the sclera, or white part, of the human eye. Rather than being injected into the tissue, the dye is injected between two layers of the eye, then gradually spreads. The process remains uncommon due to professionals' discomfort performing the procedure [1] and is illegal in the American states ...
Cephalopod ink. Ventral view of the viscera of Chtenopteryx sicula, showing the specific location of the ink sac. Cephalopod ink is a dark-coloured or luminous ink released into water by most species of cephalopod, usually as an escape mechanism. All cephalopods, with the exception of the Nautilidae and the Cirrina (deep-sea octopuses), [1] are ...
Iron gall ink. Iron gall ink (also known as common ink, standard ink, oak gall ink or iron gall nut ink) is a purple-black or brown-black ink made from iron salts and tannic acids from vegetable sources. It was the standard ink formulation used in Europe for the 1400-year period between the 5th and 19th centuries, remained in widespread use ...
Carbon black ( Color Index International, PBK-7) is the name of a common black pigment, traditionally produced from charring organic materials such as wood or bone. It appears black because it reflects very little light in the visible part of the spectrum, with an albedo near zero.
Sulfur dyes are the most commonly used dyes manufactured for cotton in terms of volume. They are inexpensive, generally have good wash-fastness, and are easy to apply. Sulfur dyes are predominantly black, brown, and dark blue. [1] Red sulfur dyes are unknown, although a pink or lighter scarlet color is available.

t. e. Dye-sublimation printing (or dye-sub printing) is a term that covers several distinct digital computer printing techniques that involve using heat to transfer dye onto a substrate. The sublimation name was first applied because the dye was thought to make the transition between the solid and gas states without going through a liquid stage.
A leuco dye (from the Greek λευκό leuko: white ) is a dye which can switch between two chemical forms, one of which is colorless. Reversible transformations can be caused by heat, light or pH, resulting in examples of thermochromism, photochromism and halochromism respectively. Irreversible transformations typically involve reduction or ...
