Carmine ()also called cochineal (when it is extracted from the cochineal insect), cochineal extract, crimson lake, or carmine lake is a pigment of a bright-red color obtained from the aluminium complex derived from carminic acid. Specific code names for the pigment include natural red 4, C.I. 75470, or E120. Carmine is also a general term for a particularly deep-red color.

Alizarin (also known as 1,2-dihydroxyanthraquinone, Mordant Red 11, C.I. 58000, and Turkey Red) is an organic compound with formula that has been used throughout history as a red dye, principally for dyeing textile fabrics. Historically it was derived from the roots of plants of the madder genus. In 1869, it became the first natural dye to be produced synthetically.

Crimson is a rich, deep red color, inclining to purple.

Gamboge ( ) is a deep-yellow pigment derived from a species of tree that primarily grows in Cambodia. Popular in East Asian watercolor works, it has been used across a number of media dating back to the 8th century. Easy to transport and manipulate into a durable watercolor paint, gamboge is notable for its versatility as a pigment in how it has been used in paintings, printing of books, and garment dyes, including the robes of Buddhist monks. Gamboge is toxic to humans, and is potentially deadly in large doses. Due to its toxicity and poor lightfastness, gamboge is no longer used in paints, t

Quinacridone is an organic compound used as a pigment. Numerous derivatives constitute the quinacridone pigment family, which finds extensive use in industrial colorant applications such as robust outdoor paints, inkjet printer ink, tattoo inks, artists' watercolor paints, and color laser printer toner. As pigments, the quinacridones are insoluble. The development of this family of pigments supplanted the alizarin dyes.

Anthoxanthins are water-soluble pigments which range in color from a white or colorless to a creamy to a yellow, often on petals of flowers. These pigments are generally whiter in an acid medium and yellowed in an alkaline medium. They are very susceptible to color changes with minerals and metal ions, similar to anthocyanins. Some examples of anthoxanthins include: apigeniun, luteolin, kaempferol, quercetin.
