The effects of stimuli sizes on colour appearance for unrelated colour under photopic and mesopic vision
This study investigates the change of colour appearance between different sizes of unrelated colours under different luminance levels. Six phases of psychophysical experiments were conducted to obtain visual data assessed by a panel of observers. The viewing conditions studied included two stimuli sizes (0.5° and 10°) and three luminance levels (60, 5 and 1 cd/m<2>. It was found that colours in general appear brighter and more colourful for 10° stimuli than those for 0.5° stimuli. Under lower luminance levels, 5 and 1 cd/m<2>, the colourfulness was similar between the two different stimuli sizes studied.
