the colour characteristics of a lamp are defined by the colour appearance and the colour rendition (or rendering)
NOTE 1 The actual colour of the lamp is called colour appearance and is defined in terms of the spectral tristimulus values (colour co-ordinates) according to the recommendations of the IEC.
NOTE 2 The spectral characteristics of the light emitted by the lamp have an effect on the appearance of the objects it illuminates; this effect is called rendition. |
