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 .
The colour blood red is a dark shade of the colour red meant to resemble the colour of human blood (which is composed of oxygenated red erythrocytes, white leukocytes, and yellow blood plasma). [2] It is the iron in hemoglobin specifically that gives blood its red colour.
Some LCD projectors use dichroic filters instead of prisms to split the white light from the lamp into the three colours before passing it through the three LCD units. Six-segment dichroic color wheel from a DLP projector. Segments transmit red, green and blue, and therefore reflect cyan, magenta, and yellow.
Highly oxidized red soil in Tirunelveli District, India. Red colors often indicate iron accumulation or oxidation in oxygen-rich, well-aerated soils. [4] Iron concentrations caused by redox reactions because of diffusion of iron in crystalline and metermorphic rock,in periodically saturated soils may also present red colors, particularly along root channels or pores.
Nicol prisms produce a very high purity of polarized light, and were extensively used in microscopy, though in modern use they have been mostly replaced with alternatives such as the Glan–Thompson prism, Glan–Foucault prism, and Glan–Taylor prism. These prisms are not true polarizing beamsplitters since only the transmitted beam is fully ...
If the emission or reflection spectrum of a color is 1 (100%) for all the wavelengths between A and B, and 0 for all the wavelengths on the other half of the color space, then that color is a maximum chroma color, semichrome, or full color (this is the explanation to why they were called semichromes). So maximum chroma colors are a type of ...
These correlations are commonly stylized and conventionalized, so that the color with the most intuitive meaning is often the nearest prototypical named color rather than that most similar to the real-world color (e.g., in very rare locations, water depth is symbolized using different shades of the color blue). Common, but by no means ...
Modern glasses are typically supported by pads on the bridge of the nose and by temple arms placed over the ears. Historical types include the pince-nez, monocle, lorgnette, and scissors-glasses. Eyeglass lenses are commonly made from plastic, including CR-39 and polycarbonate. These materials reduce the danger of breakage and weigh less than ...
