2. Color rendering index - Wikipedia

   en.wikipedia.org/wiki/Color_rendering_index

   A color rendering index (CRI) is a quantitative measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with a natural or standard light source. Color rendering, as defined by the International Commission on Illumination (CIE), is the effect of an illuminant on the color appearance of objects by ...

3. Color rendering - Wikipedia

   en.wikipedia.org/wiki/Color_rendering

   The color rendering of a light source refers to its ability to reveal the colors of various objects faithfully (i.e. to produce illuminant metamerism) in comparison with an ideal or natural light source. Light sources with good color rendering are desirable in color-critical applications such as neonatal care [1] and art restoration.

4. High-CRI LED lighting - Wikipedia

   en.wikipedia.org/wiki/High-CRI_LED_lighting

   Color Rendering Index (CRI) is determined [9] by the distinctions in the chromaticities of fifteen test color samples (TCS), where objects are illuminated by the light source to be evaluated and a reference illuminant with the same CCT. The higher the CRI value, the smaller the differences between indices will be.

5. Metamerism (color) - Wikipedia

   en.wikipedia.org/wiki/Metamerism_(color)

   A classic example is the automobile industry: the colorants used for interior fabrics, plastics and paints may be chosen to provide a good color match under a cool white fluorescent source, but the matches can disappear under different light sources (e.g. daylight or tungsten source). Furthermore, because of the differences in colorants ...

6. Color quality scale - Wikipedia

   en.wikipedia.org/wiki/Color_Quality_Scale

   Color quality scale (CQS) is a color rendering score – a quantitative measure of the ability of a light source to reproduce colors of illuminated objects. Developed by researchers at NIST [1] the metric aims to overcome some of the issues inherent in the widely used color rendering index (CIE Ra, 1974).

7. Kruithof curve - Wikipedia

   en.wikipedia.org/wiki/Kruithof_curve

   The color rendering index of a given source is a measure of that source's ability to faithfully reproduce colors of an object. Light sources, like candles or incandescent light bulbs produce spectrums of electromagnetic energy that closely resemble Planckian black bodies; they look much like natural sources.

8. Ceramic metal-halide lamp - Wikipedia

   en.wikipedia.org/wiki/Ceramic_metal-halide_lamp

   The metallic atoms are the main source of light in these lamps, creating a white light with a CRI (color rendering index) of up to 96. The exact correlated color temperature and CRI depend on the specific mixture of metal halide salts. There are also warm-white ceramic metal halide lamps, with somewhat lower CRI (78-82) which still give a more ...

9. Radiosity (computer graphics) - Wikipedia

   en.wikipedia.org/wiki/Radiosity_(computer_graphics)

   There is only one source of light: an image of the sky placed outside the window. The difference is marked. The room glows with light. Soft shadows are visible on the floor, and subtle lighting effects are noticeable around the room. Furthermore, the red color from the carpet has bled onto the grey walls, giving them a slightly warm appearance.
