The color of red and other pigments is determined by the way it absorbs certain parts of the spectrum of visible light and reflects the others. The brilliant opaque red of vermillion, for example, results because vermillion reflects ...
B: Normalized to [0–255] (byte) Venetian red is a light and warm (somewhat unsaturated) pigment that is a darker shade of red. The composition of Venetian red changed over time. Originally it consisted of natural ferric oxide (Fe 2 O 3, partially hydrated) obtained from the red hematite. Modern versions are frequently made with synthetic red ...
Perinone. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Perinone is a class of organic compounds. The parent compound has two isomers, each of which are useful pigments. It is prepared from naphthalenetetracarboxylic dianhydride by condensation with o -phenylenediamine.
Iron oxide pigments in jars: yellow, red, brown. Iron oxide red is a generic name of a ferric oxide pigment of reddish colors. Multiple shades based on both anhydrous Fe2O3 and its hydrates were known to painters since prehistory. The pigments were originally obtained from natural sources, since the 20th century they are mostly synthetic.
Toluidine red is an organic compound with the formula C10H6(OH) (N2C6H3(NO2)CH3). A dark red solid, the compound is classified as a azo dye consisting of a 2-naphthol group linked to a 2-nitro-4-methylphenyl substituent. [3] Toluidine red is a traditional pigment, found in oil paints. [4] Although once popular, it suffers as a pigment owing to ...
Red (RGB), RGB red, or electric red[citation needed] (as opposed to pigment red, shown below) is the brightest possible red that can be reproduced on a computer monitor. This color is an approximation of an orangish red spectral color. It is one of the three primary colors of light in the RGB color model, along with green and blue.
Cerium sulfide red (PR265). Iron oxide pigments. Sanguine, Caput mortuum, Indian red, Venetian red, oxide red (PR102). Red ochre (PR102): anhydrous Fe 2 O 3. Burnt sienna (PBr7): a pigment produced by heating raw sienna. Lead pigments. Minium (pigment): also known as red lead, lead tetroxide, Pb 3 O 4. Mercury pigments.
Realgar was, along with orpiment, traded in the Roman Empire and was used as a red paint pigment. Early occurrences of realgar as a red paint pigment are known for works of art from China, India, Central Asia, and Egypt. It was used in European fine-art painting during the Renaissance era, a use which died out by the 18th century. [14]
