Color science is the scientific study of color including lighting and optics; measurement of light and color; the physiology, psychophysics, and modeling of color vision; and color reproduction. It is the modern extension of traditional color theory .
Since color is such an important element in how people interpret their environment, color psychology can enhance the feeling of immersion in people that play video games. By using color psychology to cause immersion in players, players can have fewer errors playing video games in comparison to a game that does not utilize color psychology ...
The pigments may be added at the concrete mixer. Alternatively, to guarantee repeatable color, some manufacturers supply ready-blended colored cements, using white cement as a base. To be "white", the powdered material must have a reflectance value ( "L value" ) in excess of 85%.
Pigments for sale at a market stall in Goa, India. A pigment is a powder used to add color or change visual appearance. Pigments are completely or nearly insoluble and chemically unreactive in water or another medium; in contrast, dyes are colored substances which are soluble or go into solution at some stage in their use.
The pigment was valued for its quality and the genuine product was marked with a seal to show its authenticity. In the Renaissance "sinopia" or "sinoper" meant any of a range of different shades and hues, and the colour had a variety of names; it was sometimes called Venetian red , or Terra di Siena (Sienna earth), or Ocra rosso (red ochre).

Color theory, or more specifically traditional color theory, is a historical body of knowledge describing the behavior of colors, namely in color mixing, color contrast effects, color harmony, color schemes and color symbolism. [1] Modern color theory is generally referred to as color science.
The higher pressure of 10,000 kPa (1,500 psi) permits a thicker pigment layer to be embedded into the cement layer. The pigment layer is usually 3–4 mm (0.12–0.16 in) thick. Another difference is the quality of the pigments used. High-quality producers use mineral-based pigments only. Non-mineral-based pigments fade with age.
All of these agents of deterioration hinder the effectiveness of the Munsell color system, which directly matches pigment shades. The Munsell color system is a scientific system in which colors have been ranged into a color fan based upon three attributes: hue or color, the chroma or color saturation, and the value or neutral lightness or darkness.
