Many of the colors were discovered unintentionally while scientists were seeking to create other chemical products. Colorants such as pthalo blues and greens, the quinacridone reds and violets, the arylide yellows, and aniline colors. Many of these colors show various levels of transparency, have vivid or intense colors, and high tinting energy.

They typically encompass a very finely ground solid pigment, a surfactant, emulsifiers like glycols, and water.

These mixtures are ground in pigments dispersion equipment until a smooth even color mix is received. Typically, these tints are used at 5% concentration to paint medium or less.
