Psychophysical study of colour
Colour plays an important role in many practical tasks related to choice, identification, and as linguistic elements of the visual communication system. Colour memory is also one of the factors responsible for the phenomenon of colour constancy. Psychophysical methods and procedures are useful in determining threshold, including visual field analysis. A psychophysical experiment was carried out for describing colour appearance under different viewing conditions. Measurement of visual response can be achieved through several methods. In this paper the method of constant stimuli is applied. Analysis were made on the base of comparisons with visual evaluation as well as instrumental CIE L*a*b* evaluation (L*, C* and H* colour values). Yellow and blue hues were the chosen samples. Yes or No response presents a stimulus. Correct response can range from 0% to 100% as shown as stimulus intensity vs. percentage seen. The results obtained, presented in a CIE L*a*b* through C*/L* and a*/b*, showed more disagreement of visual evaluation compared with instrumental evaluation in the area of yellow than blue.
