The size of the colour stimulus has an effect on colour perception. To investigate this in detail, an experiment was conducted with the help of a PDP monitor (to display a large colour stimulus) and a CRT monitor (to display the same colour stimulus but of smaller size). Observers viewed a large and corresponding slightly different small colour stimuli several times, immediately after each other. They had to decide whether their colour perception was the same. All stimuli were measured in-situ by the aid of a spectro-radiometer. Aim of this work was to get a reliable visual dataset for the colour size effect for this colour point.
