3.1

visual sensory assessor, noun

observer, noun

any person taking part in a sensory evaluation of product colour

Note 1 to entry: Adapted from ISO 5492:2008, 1.5.

3.2

hue

attribute of a visual sensation according to which an area appears to be similar to one of the perceived colours, red, yellow, green and blue, or to a combination of two of them

[SOURCE:IEC 60050-845|CIE 17:1987, 02-35]

3.3

photopic vision

vision by the normal eye when it is adapted to levels of luminance of at least several candelas per square metre

Note 1 to entry: The cones are the principal active photoreceptors in photopic vision.

[SOURCE:IEC 60050-845|CIE 17:1987, 02-09]

3.4

metameric colour stimuli

metamers

spectrally different colour stimuli that have the same tristimulus values

Note 1 to entry: The corresponding property is called “metamerism”.

[SOURCE:IEC 60050-845|CIE 17:1987, 03-05]

3.5

colour rendering

effect of an illuminant on the colour appearance of objects by conscious or subconscious comparison with their colour appearance under a referent illuminant

[SOURCE:IEC 60050-845|CIE 17:1987, 02-59)]

3.6

colour rendering index

measure of the degree to which the psychophysical colour of an object illuminated by the test illuminant conforms to that of the same object illuminated by the reference illuminant, suitable allowance having been made for the state of chromatic adaptation

[SOURCE:IEC 60050-845|CIE 17:1987, 02-61]

3.7

colour matching

action of making a colour stimulus appear the same in colour as a given colour stimulus

[SOURCE:IEC 60050-845|CIE 17:1987, 02-61]

3.8

luminance threshold

lowest luminance of a stimulus which enables it to be perceived

Note 1 to entry: The value depends on field size, surround, eye state of adaptation (pupil), and other viewing conditions.

[SOURCE:IEC 60050-845|CIE 17:1987, 02-45]

3.9

defective colour vision

anomaly of vision in which there is a reduced ability to discriminate between some or all colours

[SOURCE:IEC 60050-845|CIE 17:1987, 02-13]

3.10

viewing conditions

conditions under which a visual observation is made, including the angular subtense of the specimen at the eye, the geometric relationship of source, specimen, and eye, the photometric and spectral character of the source, the photometric and spectral character of the field of view surrounding the specimen, and the state of adaptation of the eye

[SOURCE:ASTM E284:2009 ^[7] ]

3.11

chromatic colour

perceived colour possessing hue

Note 1 to entry: In everyday speech, the word “colour” is often used in this sense to differentiate from white, grey or black.

Note 2 to entry: The adjective “coloured” usually refers to chromatic colours.

Note 3 to entry: Adapted from IEC 60050-845|CIE 17:1987, 02-27.

3.12

chromatic adaptation

change in visual hue after viewing coloured surfaces or lights

3.13

adaptation

process allowing the eye to function in a wide range of illuminance levels by modifying its sensitivity through changes in pupil aperture and photochemical changes in the retina

Note 1 to entry: Adaptation to darkness takes longer than adaptation to brightness.

3.14

daylight illuminant

illuminant having the same or nearly the same relative spectral power distribution as a phase of daylight

[SOURCE:IEC 60050-845|CIE 17:1987, 03-11]

3.15

illuminance (at a point on a surface)

ratio of the luminous flux incident on an element of surface that contains the point and the area of that element

[SOURCE:IEC 60050-845|CIE 17:1987, 10-100]
