- Pigment code
- PR179
- Type
- organic, anthraquinone
- Chemical formula
- C26H14N2O4
- Properties
- Perylene Maroon is a transparent, dull to moderately dull, deep red pigment. Its transparency makes it useful as a glazing color. Its mixing complement is Phthalo Green, and together they produce a pure black that is darker than most carbon-based pigments.
- Permanence
- Perylene Maroon has excellent permanence and lightfastness, and it can be an appropriate replacement for Anthraquinone Red in watercolor form.
- Toxicity
- Perylene Maroon has no significant acute toxicity. Its long term hazards are currently unknown.
- History
- Perylenes have been used as vat dyes since 1912, but they were not manufactured and sold as pigments until 1957.

Quinacridone Violet
- Pigment code
- PV19
- Type
- organic synthetic, quinacridone

Quinacridone pigments have relatively low tinting strength in general. For this reason, quinacridone colors are often expensive, because more pigment is required in the formulation.
