The instant disclosure generally relates to a coloring composition for coloring mammalian or synthetic keratin fibers or keratinous surfaces. The composition comprising a medium, optionally pigment microparticles and at least one dye, in particular at least one peri-arylene dye dissolved in the medium. Methods of using such compositions are also described herein.

Highly saturated scarlet dye ink for a high-speed inkjet process and a method of preparing the highly saturated scarlet dye ink are disclosed. In particular, an ink composition according to the present invention includes a dye including a compound represented by Formula 1, and further includes, in addition to the dye, distilled water, a surfactant, and an additive. The ink composition develops a highly saturated scarlet color that is unable to be developed by existing inks for digital textile printing (DTP), and has high water solubility, excellent heat resistance, and light-fastness, and thus may be effectively used as dye and ink for a high-speed inkjet process. ##STR00001##
