In astronomy, the color index is a simple numerical expression that determines the color of an object, which in the case of a star gives its temperature. The lower the color index, the more blue (or hotter) the object is. Conversely, the larger the color index, the more red (or cooler) the object is.
A 2-bit indexed color image. The color of each pixel is represented by a number; each number (the index) corresponds to a color in the color table (the palette).. In computing, indexed color is a technique to manage digital images' colors in a limited fashion, in order to save computer memory and file storage, while speeding up display refresh and file transfers.
Colour Index International (CII) is a reference database jointly maintained by the Society of Dyers and Colourists and the American Association of Textile Chemists and Colorists. [1] It currently contains over 27,000 individual products listed under 13,000 Colour Index Generic Names. [ 2 ]
A color–color diagram is a means of comparing the colors of an astronomical object at different wavelengths. Astronomers typically observe at narrow bands around certain wavelengths, and objects observed will have different brightnesses in each band.
So, generally, it is regarded as a supplement of color rendering index when evaluating a high-CRI light source. R9 value, TCS 09, or in other words, the red color is the key color for many lighting applications, such as film and video lighting, textile printing, image printing, skin tone, medical lighting, and so on.
The DSM Yolk Color Fan is a 16-scale color index that distinguishes yolk color and is widely used in the poultry industry. Under the scale, each number corresponds with a different shade. Number ...
Color temperature is a parameter describing the color of a visible light source by comparing it to the color of light emitted by an idealized opaque, non-reflective body. The temperature of the ideal emitter that matches the color most closely is defined as the color temperature of the original visible light source.
