The degree of warmth or coolness of a light source associated with its colour, expressed in kelvins. 5, record 1, English, - colour%20temperature

Basically, colour temperature describes the colour appearance of a light source. Sources with low colour temperature (below 3000 K) are described as "warm," and lean towards the red side of the spectrum. High colour temperature sources (above 4 000 K) are more bluish and are described as "cool". 6, record 1, English, - colour%20temperature
Record number: 1, Textual support number: 1 OBS
chromaticity: More recently, the term "chromaticity" has been used in place of color temperature. Chromaticity is expressed either in Kelvins (K) or as "x" and "y" coordinates on the CIE Standard Chromaticity Diagram. 4, record 1, English, - colour%20temperature

La température de couleur caractérise l'aspect chromatique d'une source lumineuse. Les sources [...] chaudes, c'est-à-dire celles dont la température de couleur est faible (inférieure à 3000 K), se situent du côté rouge du spectre. Les sources [...] froides, c'est-à-dire celles dont la température de couleur est élevée (supérieure à 4000 K), tendent plutôt vers le bleu. 4, record 1, French, - temp%C3%A9rature%20de%20couleur
Record number: 1, Textual support number: 2 CONT
Deux paramètres indépendants servent à décrire la couleur des sources lumineuses : la température de couleur (ou la température de couleur proximale, dans le cas des lampes fluorescentes) et l'indice de rendu des couleurs. La température de couleur est utilisée dans le cas des radiateurs à haute sélectivité, comme les lampes à décharge électrique, lorsque la lumière du radiateur a environ les mêmes coordonnées de chromaticité qu'un corps noir à une température donnée. 4, record 1, French, - temp%C3%A9rature%20de%20couleur
