About: Color rendering

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

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 and art restoration. It is defined by the International Commission on Illumination (CIE) as follows: Color rendering: Effect of an illuminant on the color appearance of objects by conscious or subconscious comparison with their color appearance under a reference illuminant.

  • 演色性（えんしょくせい）とは、ランプなど発光する道具・装置が、ある物体を照らしたときに、その物体の色の見え方に及ぼす光源の性質のこと。 一般的に自然光を基準として、近いものほど「良い」「優れる」、かけ離れたものほど「悪い」「劣る」と判断されるが、演色性に正確性を要求されるような専門的分野においては、数値化された客観的判断基準が設定されていることが多く、演色評価数（えんしょくひょうかすう、英：Color Rendering Index、略称：CRI）がこれにあたる。 (ja)
