When there are significantly more blue pigments in the violet than there are red pigments, a blue-based shade of violet develops. These shades include blue-violet, indigo, han purple, iris and Persian blue. Periwinkle consists of a blue-based violet mixed with white pigments. Blue-based violet plus black pigments result in the shade of eggplant. Because of their primarily blue base, all of these shades are considered cool colors, and are commonly used with other cool colors in paintings.
Violets that are red-based contain significantly more red pigment than blue pigment. These colors are often considered pinks. The commonly identified shades of red-based violets include cerise, fandango, fuchsia, magenta, red-violet, rose and sangria. These shades are considered warm colors, and are used with other warm colors in paintings and other works of craft and art. Tyrian purple is another red-based violet, but it is created by adding black pigment to a red-based violet. Adding white pigment to a red-based violet forms a light rose shade.
When the amounts of red and blue pigment in a violet are balanced but white pigment is added, new violet shades develop. These are sometimes considered light violet or, generically, lavender. Lavender is actually a specific shade of violet. Other shades of violet that include white pigments are amethyst, heliotrope, lavender floral, lavender blush, lilac, mauve, orchid, thistle and wisteria.
When black pigment is added to violet, darker shades of violet are created. These shades can be blue-based or red-based. In some cases, shades that combine red, blue and black pigments may appear black or brown to the untrained eye. Shades of violet that include black pigment are Byzantium, eggplant, palatinate purple, regalia, Tyrian purple and purple.
