Solution

The main advantage of gel ink is its high viscosity, which supports a higher proportion of pigments in the medium. The pigments are typically copper phthalocyanine and iron oxides, and the gel is made up of water and biopolymers, such as xanthan gum and tragacanth gum, as well as some types ofpolyacrylate thickeners. The pigments are opaque, and gel pens are available in a rainbow of bright and pastel colours, as well as opalescent, metallic, and glittery colours which show up clearly on dark paper.
