Critical components of any color are pigments. The paint is often perceived by the person as a mixture of pigments and binders – linseed oil, emulsion, latex. Rarely thinks about how he created or different color. And it's useful to know, because the elements that make up the color may different ways to behave in certain conditions. For example, some pigments from the effects of temperature change color. Mixing Pigments in certain proportions, can produce different colors, shades and properties of paint. Pigments are natural and synthetic. Natural – a natural material consisting of minerals.
Ingoda they are subjected to temperature processing. But artificial materials generally have a more vivid, well-defined color. The main property of the pigments, which must take into account when creating a paint, a coloring power. It determines how a particular color of paint you need to transfer color when mixed with white pigment. By natural pigments include: graphite, chalk, ocher, sienna, umber. Chalk – a common mineral, often used in waterborne, alkyd, oil paints. Also, the white pigments include lime. Black pigments – graphite, charcoal, manganese peroxide.
Natural yellow pigment formed from the ocher. And the colors can vary (from barely noticeable lemon to orange), depending on heat treatment. To get brown paint used umber, burnt sienna. Under the influence of temperature changes the color of umber, acquires red. Artificial pigments, often more expensive than natural ones. But they are highly resistant to external influences, as well as they do not lose color saturation for a long time. For synthetic dyes include red lead, white lead, chromium oxide, crown, green, mummy, Mars, cobalt, vermilion, ultramarine blue, black, paint for facades made on these pigments. White – the basic, commonly used pigment white. There are zinc, lead, titanium white. White lead because of toxicity are rarely used in domestic work. Whiting, obtained from zinc oxide, are a frequent component of the enamel and oil paints. Most high levels of resistance, opacity – a titanium white. However, they also have their own feature – a gradual color change, the acquisition of a yellowish tinge. Therefore, in the paint with pigments are often added blue dyes. The basic black dye is black, the resulting combustion with insufficient oxygen. Pigments in red – vermilion, mummy. The mummy eventually loses saturation of red, dim. Cinnabar is toxic because of mercury content. Minium has orange-red. Minium-based paint Lead from the released toxins are rarely used indoors. Mars provide an opportunity to get several warm shades – from yellow to red brown. To obtain a yellow crown use – lead, strontium, zinc. Lead crown harmful as other paints with a similar basis. Blue pigments colors are blue, cobalt, ultramarine. Green color is formed by adding zinc or lead paint pigment green. It in turn is made by mixing paint and yacht crown (yellow). Independently mix pigments found in its pure form is extremely dangerous. Dust clouds, falling into the organism can cause serious damage to health.
