What is the color rendering index& why does it mater?

 

Render means to make , cause , or become.For example, to be rendered sick means you have become ill, and to be rendered speechless means something has mde you speechless.When an object's  colour is rendered, it means how the light makes the colour appear , or the colour that light makes an object appear. 

 

What is CRI? 

The colour rendering index is a scale of 0 to 100 that rates the ability of an artifical whle light source to accurately ddisplay colour: 

 

An index score of 100 indicates that the light is showing colours as they would appear in natural daylight- as accurately as possible. 

Above 90 is exceptional, displaying colours as accurately or nearly as accurately as daylight

Between 80 and 90 is a good range that renders colours quite accurately.Many new LED light bulbs successfully achieve this index rating. 

As the index drops lower than 79, light renders colours less and less accurately to the human eye.Below 50 will be quite noticeably inaccurate.
