	Colour rendering is ‘The ability of a light source to show surface colours as they should be, usually in comparison with a tungsten or daylight source. Measured on the [[Color_Rendering_Index\|colour rendering index (CRI)]] scale. A value of 0 means it is impossible to discern colours at all, and a score of 100 means no colour distortion. For most indoor lighting applications a value of at least 80 is recommended.’		Colour rendering is ‘The ability of a light source to show surface colours as they should be, usually in comparison with a tungsten or daylight source.

	Colour appearance refers to the ‘…visual sensation correlated with the ‘warmth’ or ‘coolness’ of the light emitted by a lamp. The metric used to characterise the colour appearance of the light emitted by a light source is the correlated colour temperature (CCT), expressed in Kelvin (K). Warm white light is produced by lamps having a colour temperature below 3,000 K (reddish hues), whereas 4,000 K and above (bluish) is cool and cold white light. The colour appearance is quite separate from the colour rendering of the lamp.’		Colour appearance refers to the ‘…visual sensation correlated with the ‘warmth’ or ‘coolness’ of the light emitted by a lamp.
