brightness 

Attribute of visual sensation according to which an area appears to emit more or less light. Syn. luminosity. Note 1: In British recommended practice, the term brightness is now reserved to describe brightness of colour (i.e. the opposite of dullness) as used in the dyeing industry. Note 2: This attribute is the psychosensorial correlate, or nearly so, of the photometric quantity luminance (CIE).
